The depiction appears towards the end of the video, asserting debunked claims that the 2020 election - which he lost to Joe Biden - was stolen from him.
Posted on Mr Trump's own social media network, the two-second clip shows the Obamas as apes bobbing up and down to the tune of "The Lion Sleeps Tonight".
The post was later deleted - around 12 hours after being posted.
A White House official said a member of staff "erroneously made the post" and it has now been taken down.
In a message on X, formerly Twitter, Gavin Newsom, the Democratic governor of California, accused the president of "disgusting behaviour" over the post.
He added: "Every single Republican must denounce this. Now."
Responding to the video, Senate Democratic leader Chuck Schumer wrote on X: "Racist. Vile. Abhorrent. This is dangerous and degrades our country-where are Senate Republicans?"
Mr Schumer urged the US president to apologise to the Obamas, calling the couple "two great Americans who make Donald Trump look like a small, envious man".
Ben Rhodes, who served as deputy national security adviser in the Obama White House, reacted to the video by calling Trump "a stain on our history".
"Let it haunt Trump and his racist followers that future Americans will embrace the Obamas as beloved figures while studying him as a stain on our history," he wrote on X.
George Conway - ex-husband of Kellyanne Conway, who managed the president's successful election campaign in 2016 - responded by highlighting an article he'd written describing Trump as a "racist" in 2019.
The group Republicans Against Trump wrote: "There's no bottom."
Before the post was removed, White House press secretary Karoline Leavitt defended it and said the depiction formed part of a longer video depicting various politicians as animals.
She said: "This is from an internet meme video depicting President Trump as the King of the Jungle and Democrats as characters from The Lion King.
"Please stop the fake outrage and report on something today that actually matters to the American public."
Mr Trump has a long history of attacking Mr Obama, his predecessor as president, and was a vocal proponent of the "birther" conspiracy theory.
The theory cast doubt on Mr Obama's birth in Hawaii, asserting that he was actually born in Kenya, and therefore ineligible to hold the office of president.
Mr Obama produced his long-form birth certificate in 2011. In 2016 Mr Trump publicly accepted that his predecessor was born in the USA.

Leicester Crown Court heard Jon Ruben, 76, who ran a camp for at least 27 years, was arrested in July 2025 after eight children were taken to hospital.
Liquid Xanax was found to have been used on some of the victims at Stathern Lodge in Leicestershire.
The former vet admitted drugging and abusing two boys - pleading guilty to sexual assault of a child under 13, assault of a child under 13 by penetration, eight counts of child cruelty, three counts of making indecent images of children and four drugs charges.
Ruben from Ruddington, Nottinghamshire, this week also admitted a further charge of drugging his wife Susan with temazepam so she would not wake while the abuse took place.
On Friday, she told his sentencing he was "a sadistic, monstrous, paedophile" who had spent decades "trying to paint a picture that he was a righteous, honourable man".
She said she felt "terribly guilty" about what he had done.
Baby oil and syringes
At one point, Ruben shouted "no" and cried as he heard the prosecution outline the facts of the case and was told by the judge to restrain himself.
He was jailed for 23 years and 10 months and will serve a further eight years on licence.
Judge Timothy Spencer KC told the court: "This was the deliberate drugging of boys aged between eight and 11 years to facilitate sexual assaults without detection, and the harm is at the highest level."
The court previously heard Ruben's stepson had raised concerns during the camp after finding baby oil, syringes containing white powder and other items.
The prosecution said the children fell ill after playing a so-called sweet game and found it difficult to walk, had slurred speech and could not wake up.
Prosecutor Mary Prior KC said the next morning some were "walking into walls and in the wrong direction".
Xanax's effects can start after about half an hour and last up to six hours.
Ms Prior said Ruben had "used his cloak of Christianity and his position of authority and trust" to poison and abuse boys as young as eight at the camp - located eight miles north of Melton Mowbray.
'Devious sexual predator'
The prosecution said Ruben had used his skill as a vet to illegally purchase sedatives, research quantities, and crush and inject drugs into very sweet and sticky sweets.
Ruben leaned forward in the dock with his head in his hands as graphic details of the abuse were described to the court on Friday. He was heard crying and saying: "I'm sorry".
The mother of one of the children said her son had "shut down and started self-harming", while another victim's mother called him a "devious sexual predator".
The father of one victim told the court his son "admired and respected" Ruben and because the camp was a Christian event they "were confident it would be safe", but they had been "betrayed".
Another father described being "unbelievably angry" seeing his son in hospital after he had been drugged and said he "looked like a zombie".
Addressing Ruben, a child's mother called him a "disgusting, vile man" who had "ruined the lives of these children".
She added: "I want you to suffer every day."

Temporary Detective Chief Inspector Neil Holden described Ruben as a "vile, horrific offender" who "tried to blame others things, other factors, other people" for his abuse.
He said Ruben had worked in schools, youth organisations and summer camps for at least 20 years and the force is urging any more victims or witnesses to come forward.
The owners of Stathern Lodge are independent from those who use or hire it and were not connected to the incident, Leicestershire Police confirmed.
They stretch back decades but their effect has been immediate. All week we have said that being mentioned in the files is not evidence of wrongdoing, and that remains a true and important point.
But the release has permanently tarnished reputations and, at the very least, raised questions about supposedly clever people's judgement.
It has cost Peter Mandelson his seat in the Lords, and who knows what will come of the police investigation now launched. And it has left many others with questions to answer.
There is no evidence to suggest wrongdoing by the tech moguls Bill Gates and Elon Musk, for example.
But the files show that both, like Mandelson, associated with Epstein after his conviction for child prostitution. Sarah Ferguson took her daughters to meet Epstein in Miami the week after his release for that very offence.
Sarah Ferguson has previously said her involvement with Epstein was "a gigantic error of judgment".
Andrew Mountbatten-Windsor's long and close relationship with Epstein does not need recounting.
Some, like Mandelson, have argued that they didn't have the full picture of Epstein's crimes. But the files also show that many people refused to have anything to do with Epstein after his conviction.
They didn't need to know every detail to understand, like Melinda Gates did in just one meeting, that Epstein was "evil personified".
We do now have the full picture, or as full as we can hope for, and it is bleak.
It is the experiences of the survivors - or victims, because not everyone survived, like Virginia Giuffre who died last year - that haunts the documents.
Much of the files look dry and methodical, including one which details some witnesses interviewed by authorities, but on closer inspection you can see it is their high schools that are listed; all are 17, and between them they were abused hundreds of times.

Or the victim who took a pen to the title of her journal, "Flights of fancy", and altered it to read "Flights and yachts of horror". Or the testimony of Lisa Phillips, who spoke to Sky News this week:
"One of the young girls came to the door and said, you know, Jeffrey's ready for his massage and, I argue with the girls for a little bit because I don’t want to do a massage.
"I went with the other girl who brought me to the island. I went into the room to do this massage, and the massage turned into a sexual assault."
The great and the good visited that same island, or they sought invitations. Unlike Lisa, they had a choice.
Harper Dennis is due to appear at Leicester Magistrates' Court on Saturday, accused of murdering 20-year-old Khaleed Oladipo, Leicestershire Police said.
Mr Oladipo, a cyber security student at De Montfort University, died in hospital on Tuesday night after being stabbed in the chest.
Dennis, of West Drayton, London, is also charged with possession of an offensive weapon in a public place.
He also faces two counts of possession of an offensive weapon in a private place, which are unrelated to the murder investigation.

In a tribute, Mr Oladipo's family said they could not "begin to put into words how sad we are to have lost Khaleed".
"He was an extremely loved son, brother, uncle, boyfriend and friend," they said.
"Khaleed was a good boy who loved his family. He was in his second year at university, and we were so proud of him.
"One of his main passions was football and he had played since the age of four.
"He was an Arsenal supporter and we believe he was on his way home to watch the game later that night when he was stabbed and killed.
"We want to thank the members of the public who stopped to try and help Khaleed and the ambulance service and hospital staff who did all they could to try and save him."

Gruffalo Granny will be published on 10 September 2026.
This third instalment comes more than 20 years after Donaldson's last foray into the deep dark wood, the 2004 The Gruffalo's Child, which was a sequel to the 1999 best-selling original.
The news that she would be revisiting the character with knobbly knees, turned out toes and a poisonous wart on the end of his nose was first announced in April 2025.
Now some details about the book have been released. It will feature a visit from new character the Gruffalo Granny, with an excerpt reading: "The Gruffalo said to his daughter one day, your Gruffalo Granny is coming to stay."
The story, which will again feature illustrations by Donaldson's frequent collaborator Axel Scheffler, will also see the return of the characters from the previous two books, including Fox, Snake, Owl and Mouse.
Donaldson said: "It's always a challenge to write a sequel.
"Five years elapsed between publication of The Gruffalo and The Gruffalo's Child, and now it will be more than 20 between The Gruffalo's Child and the third book.
"I actually had the basic idea for the story a long time ago but couldn't think how to develop it.
"It was only when the National Literacy Trust, whose work I'm very impressed by, used the first two books as part of their Early Words Matter programme that I was spurred on to get my idea out of the cupboard and see once and for all if I could turn it into a really satisfying story.
"To my surprise, I managed to do just that! I was of course delighted when Axel came on board and am even more so now that I've seen the brilliant illustrations he's done for the new book.
"I really hope that children - and adults too - will enjoy the new story, as I know what a wonderful experience shared reading can be."
The Gruffalo and The Gruffalo's Child have sold more than 18 million copies combined and the books have been translated into 115 languages and dialects.
Fans got the chance to see the illustration of Gruffalo Granny when Scheffler's illustration was projected in central London and Glasgow on Friday evening.
