The meeting between the two presidents will take place after hours of air attacks by Russia on Ukraine's capital Kyiv on Saturday. At least two people died and more than 30 others were injured, according to authorities.
Mr Zelenskyy has held discussions with Mr Trump several times this year, most recently at the White House in October, as the US leads the diplomatic push to end the war that has been raging for almost four years.
This time, they will meet in Florida to discuss several issues, including territory, security guarantees and the future of the Russian-occupied Zaporizhzhia nuclear plant, the Ukrainian leader has said.
Afterwards, he will hold further talks with European leaders.
Mr Zelenskyy said he hopes the "very important" meeting with Mr Trump will be "very constructive". A 20-point peace framework and security guarantee deal to be discussed "is about 90% ready" and "a lot can be decided before the New Year", he said.
Ahead of the discussions with the US leader, the Ukrainian president made a pit-stop in Canada to meet the country's prime minister, Mark Carney.
Mr Carney announced an additional $2.5 billion of economic aid for Ukraine - and condemned Russia's latest strikes on Kyiv as acts of "barbarism".
Explosions boomed across the Ukrainian capital for hours early on Saturday as ballistic missiles and drones hit the city. In a post on Telegram, Mr Zelenskyy said Russia targeted Ukraine with almost 500 drones and 40 missiles of various types.
"There have been many questions these days," he wrote. "Where is the Russian response to the proposals to end the war, which were made by the United States and the world?"
The strikes left at least a third of the city without power, with private electricity company DTEK reporting around 500,000 families were without power at one point.

The Russian defence ministry said it carried out a "massive strike" overnight, using "long-range precision-guided weapons from land, air, and sea", as well as drones, on energy infrastructure facilities "used by the Ukrainian armed forces" and "Ukrainian military-industrial complex enterprises".
But several residential buildings were also hit, according to Ukraine's interior minister Ihor Klymenko.
Russia said the strike came in response to Ukraine's attacks on "civilian objects" in Russia.
Earlier on Saturday, its defence ministry said it had shot down seven Ukrainian drones over the Russian regions of Krasnodar and Adygeya overnight. On Saturday afternoon, the ministry said 147 more drones were shot down over a number of Russian regions.
Poland said it scrambled fighter jets and temporarily closed two of its airports in the east of the country in response to Russia's attack.
There was no violation of Polish airspace, the country's armed forces command said on X.
Meanwhile, the Kremlin said on Saturday that Russian forces had captured one town in the Donetsk region and one in Zaporizhzhia.
Both areas are heavily contested and key to Russia's territorial ambitions in the east of Ukraine.
Sky News could not independently verify the battlefield reports.
"He doesn't have anything until I approve it," is how he trailed Volodymyr Zelenskyy's upcoming visit to Mar-a-Lago.
The Ukrainian leader has spoken of a peace plan that's "90% ready" but, as the guest markets its potential, the host isn't buying - yet, at least.
Any breakthrough breaks down on Russian refusal and Donald Trump needs no reminding - it's the evergreen reality that has undermined peace efforts and tested his diplomatic muscle with Moscow, often with unflattering results.
Zelenskyy and coalition allies have talked him back from the brink - a sell-out, as they saw it, when the US floated a 28-point plan that read like a Russian wish list.
The 20-point version crafted in Kyiv includes compromise and Zelenskyy talks of a "good conversation" with Trump's envoy Steve Witkoff and son-in-law Jared Kushner, in teeing up a tete-a-tete with the man himself.
So far, so promising - but relative silence from Moscow screams otherwise.
Russian officials have made some optimistic noises but they have been measured and minimal. Vladimir Putin has barely shifted from his original position on Ukraine and there's limited expectation that will change this weekend.
Why would it?
This is a Russian leader basking in the bonhomie of a president reshaping US relations to Moscow's advantage and he senses opportunity to pursue territorial ambitions. Antagonism between the US and European allies is but another benefit to Putin of things as they are.

In such circumstances, a framework proposal that locks down his ambition, long-term, won't necessarily land well in Moscow.
Is that why he played down the significance of the Zelenskyy plan?
Not for the first time, any Russian reluctance will be a test for Donald Trump - of strength, diplomacy, and of where his loyalties lie.
Babies are still being buried in Gaza.
A five-month-old infant was wrapped in a small shroud of white tarp after an Israeli strike on a school shelter in a so-called safe zone beyond IDF control.
A 29-day-old baby was declared dead on the cold stainless steel of a table in a morgue after suffering hypothermia in his family's tent.
Children as young as 8 years old are called "suspects" by the Israel Defence Forces (IDF) and killed for venturing close to the shifting yellow line demarcating their control.
These are the scenes of devastation and despair during what is called a ceasefire in Gaza.
International journalists have been barred from independently reporting from the strip for more than two years. The drone footage of vast areas of ashen rubble is still shocking through a screen.
"It is one of the most devastated places on earth to date," says Alessandro Mrakic, the head of the United Nations Development Programme's Gaza office.
"85% of the buildings have been, either partially or totally damaged, with almost 2 million people being currently displaced."
Israel does not permit the entry of reconstruction material and heavy machinery required to rebuild homes in the current phase of the US-led peace plan.
The Coordination of Government Activities in the Territories (COGAT) unit told Sky News that "at this stage, and in line with the agreement, no reconstruction materials are being transferred into Gaza."
For Alessandro's team, rebuilding Gaza will be a mammoth effort even if Israel permits the entry of construction materials and equipment.
"In a best-case scenario, if we are equipped with the proper human resources, with the proper machinery; the very initial preliminary calculation, just to remove the volume around 60 million tons - it will take seven years."
Israeli Prime Minister Benjamin Netanyahu will soon meet with US President Donald Trump in Florida to discuss the second phase of his Gaza peace plan, as well as the future of Israel's warfronts with Iran and Lebanon.
In the lead-up to the meeting, Israel's Defence Minister Israel Katz made it clear that the IDF will not be leaving Gaza.
"We are deep inside Gaza and we will never leave Gaza, there will be no such thing. We're there to defend, to prevent what happened in the past."
He was referring to the October 7th attack in 2023, where Hamas militants bulldozed the Gaza border wall and entered Israel. More than 1,200 people, mostly civilians, were killed, and more than 250 were taken hostage by Hamas.
Health officials say over 71,200 Palestinians, including at least 20,000 children, have been killed in Israel's ensuing military assault on Gaza.
IDF operations are ongoing during the ceasefire period, and satellite images show new military outposts to the east of the yellow line demarcating Israeli control as part of phase one of Trump's peace plan.
The Sky News Data & Forensics team analysed satellite imagery, which shows that yellow blocks positioned by the IDF troops on the ground to mark their territory are 390 - 490 metres deeper into Gaza than mapped on official IDF channels.
"It basically swallows more than half of the area of the Gaza strip but since the ceasefire agreement, it has continuously changed.
"Every day it is changing, every day the yellow line swallows more land and we have so far documented that the yellow line has swallowed 53 - 54% of Gaza's land," says Maha Hussein, the Gaza-based Strategy Director of the Euro-Med human rights monitor.
"Where they have expanded the yellow line, many people are getting killed, injured and targeted by Israeli snipers, quadcopters, even artillery shelling and also airstrikes. We have documented dozens of cases of people, including children, among the victims."
One of them is 16-year-old Zahir Nasser Shamia. A video shared by his friends shows them walking near the yellow blocks when a gunshot is fired.
Another shows them running across the rubble yelling out his name. Eyewitnesses say Zahir was shot in the head by Israeli forces and then run over by a bulldozer.

Gaza City hit by floods
The IDF acknowledged shooting Zahir and shared this response regarding the incident: "IDF troops operating in the northern Gaza Strip identified two terrorists who crossed the yellow line and approached the troops, posing an immediate threat to them.
"Following the identification, the troops eliminated one of the terrorists in order to remove the threat. IDF troops in the southern command remain deployed in the area in accordance with the ceasefire agreement and will continue to operate to remove any immediate threat."
The IDF did not present evidence that Zahir was involved in terrorist activity.
The Gaza Health Ministry says that more than 400 people have been killed and 1000 injured since the start of the ceasefire on 10 October.
In another incident in an area not under Israeli control, the Gaza Martyrs School-turned-shelter in Gaza City was hit by IDF shelling.
At least six people were killed, including a five-month-old baby, in an incident the IDF said involved its troops targeting suspects to the west of the yellow line, beyond their territory.
"I don't know why they do this," says Jamal Ahmed Mohamed, a surviving relative of the family killed in the shelter.
Why would the Israelis target a building full of displaced people - with no water, no clothes and no food?"
Major Noor Aziz Ahmadzai is one of more than 1,400 Afghans and their families to have faced homelessness since being given sanctuary in the UK after the fall of Kabul in August 2021.
Conservative former security minister Tom Tugendhat has told Sky News the Ministry of Defence has "really let itself down" in not relaxing strict citizenship rules to take advantage of the training and expertise of Afghan exiles during a recruitment crisis in the British military.
Noor joined the special police at the age of 16 and worked as a translator for the British before joining the Afghan special forces.
He was picked to spend two-and-a-half years on the officer training programme at Sandhurst, the UK military academy.
In June 2015, he even gave a reading at a service of thanksgiving in St Paul's Cathedral in front of the Queen.
He ultimately rose to become deputy commander of a specialist counter-terrorism unit, which responded to suicide attacks in Kabul and was among the first on the scene of hundreds of incidents, including the murder of newborn babies and their mothers at a maternity clinic in May 2020, and the Taliban siege of the Intercontinental Hotel in January 2018.
"The Intercontinental hotel is one of the most famous hotels in Kabul, and they killed a lot of civilians there", said Noor.
"We had an order to respond to what was happening... we were joined by the British Army. We saved some diplomats and were able to bring them out.
"I started there at 12 o'clock midnight, and continued till 12 o'clock in the afternoon, until we finished the enemy. I lost one of my soldiers.
"He lost his life in my hug [in my arms]."

When the Taliban took back control in August 2021, it was a nightmare for Noor and his colleagues.
"It was a black day for all Afghans who worked with other militaries," he said.
Noor was initially arrested at a Taliban checkpoint as a member of Afghan special forces, but was released after a commanding officer claimed - falsely - that he had quit three months before.
He ran four-and-a-half miles home without shoes, his feet covered in blisters. His mother then took him to hide inside a water tank at his sister's house overnight, and he was rescued thanks to the intervention of a colleague from Sandhurst he contacted on Facebook.
"There was an attack on my home, and they shot my family members," Noor said. "My colleague thought I was dead.
"When I messaged, he told me he was crying that I was alive. He said, 'come to the airport at six in the morning'. Then I put on women's clothes, as the Taliban were stopping cars - but when they saw a woman in the car, they would leave the car alone.
"I used a woman's scarf on my head, and I went to the airport. He came to the gate to get me. My mum just pushed me. She said, 'get out of here', and so I didn't hug her one last time."
Noor grew emotional when talking about his mother, whom he hasn't seen since. Her request for asylum to join him in the UK was rejected, and he has only rarely been able to speak to her on the phone, given fears the Taliban are tracking their calls.
Life in the UK
Noor is one of 37,218 Afghans brought to the UK since August 2021 - their lives at risk at home due to their links with British forces.
But since the warm promises made by then-prime minister Boris Johnson after the Taliban takeover, the political situation here in the UK has grown rather more complicated.
The Afghan resettlement schemes have now closed to new applicants. Public attitudes have hardened amid rising numbers of asylum seekers, and some 7,300 more Afghans than expected have had to come here as a result of the highly damaging government data leak revealed over the summer.
While Afghans on the schemes have the right to work and are offered temporary accommodation for up to nine months, after that, for some, it's been a struggle.
Over the past four years, 1,405 households have reported themselves homeless to their local authorities.
At one point, Noor also ended up on the streets, but was taken in by a passing British veteran until he found work as a station security guard.
While he's very thankful to the UK for rescuing him and his colleagues, he now feels abandoned by the Ministry of Defence (MoD).
"We will never forget what the British Army did for us, they saved thousands of lives and did an amazing job," he said.
"But it's hard. My son, he will ask me, 'Dad, you did 17 years in Afghan Special Forces and what was your future when you came back to the UK?' Honestly, I don't have any answer for him.
"We have a lot of talent here, a lot of generals, colonels. They're working in pizza shops. They're working for Uber. I'm a counter-terrorism specialist. Now I'm doing a security job.
"The British Army, they spent lots of money on us. But now I don't know why the MoD are ignoring us."
Noor and many other resettled Afghan veterans would like to be able to use their skills in the British military.
But while they've been given indefinite leave to remain, they will only become eligible to apply for the army after becoming British citizens - which can't happen until they have lived here for at least five years.
'Hugely skilled and highly motivated'
Mr Tugendhat, the MP for Tonbridge, says it's a waste that they haven't been able to sign up straight away.
"We should be getting these people into our armed forces," he said. "They're hugely skilled, they're highly motivated, and we know they're loyal because they have proved their loyalty in the toughest and most dangerous situations.
"So getting them into our armed forces would be good for us. It would also be good for them. It would give them, quite rightly, the role that they want to have in our society.
"This is something that should have been delivered at the time and should be delivered now. It's been overlooked for too long.
"There are some exceptionally talented people, many of whom I either trained alongside or fought alongside for several years in Afghanistan, and frankly, the MoD has really let itself down on this."
Despite an era of growing international threat, the military is struggling with recruitment and retention. 500 more personnel left the armed forces this year than joined - an improvement on recent years, but still not enough to stop the shrinkage.
'An Afghan unit would be admitting defeat'
But military experts say creating a Gurkha-style unit of Afghan veterans would be complicated.
"There will be significant security implications - which can be worked through, but it would take time," said Ed Arnold, a senior research fellow at the Royal United Services Institute (RUSI).
"There have been security incidents in the US committed by former Afghan forces. So from a risk point of view, I don't see the MoD would be too keen at the moment.
"Secondly, there is a huge cost implication to raising entire units. They need a lot of support structure. And where they integrate, it's not actually a very easy thing to do. It can be done, but it's not easy.
"Thirdly, I think that the political signal it shows is that we're choosing to raise another unit from the Afghans, because we can't get them from Britain ourselves - it's almost admitting defeat."
A Ministry of Defence spokesperson said: "This government has committed to ensuring that all Afghans who have relocated to the UK under the ARAP scheme are supported to build their new lives.
"New arrivals on the Afghan Resettlement Programme are provided with transitional accommodation for up to 9 months, during which time they receive support to help them secure their own long-term accommodation. The government is also taking measures to minimise homelessness presentations.
"Afghans who have been relocated under this scheme are entitled to work and can access a range of employment support. Those who obtain British citizenship can apply for roles in the military, provided they meet other necessary criteria including age requirements, education specifications and medical standards."
Noor is hoping to be able to return home one day - but until then, he wants to use his hard-won skills to help his adopted country.
"My message to the British Army is - keep our talented people close to you. When you need us, we're waiting for the call. We'll stand with you shoulder to shoulder."
David Darke died in hospital on Saturday after being injured near to the Crown Inn in Appleby Magna, North West Leicestershire, on 21 December.
Leicestershire Police said a 36-year-old man initially arrested on suspicion of causing grievous bodily harm had been re-arrested on suspicion of murder.
Officers were called to the pub at about 9.45pm last Sunday.
The force said the victim was outside when he was punched and sustained a serious head injury.

Detective Inspector Kevin Hames, of the East Midlands Special Operation Murder Investigation Team, said: "The initial investigation resulted in us identifying several witnesses and examining CCTV from the area.
"Those inquiries will continue and the suspect will be re-interviewed by detectives.
"It is an extremely difficult time for Mr Darke's family and specialist officers are supporting them."
