Mr Corbyn said it was “wrong” for Theresa May to be “rewarding” outspoken White House chief Mr Trump by inviting him to Britain.
In a furious attack, the hard-left Labour leader also lashed out at the president’s “cruel and inhumane” immigration policy.
Mr Trump is today meeting Mrs May at Chequers, the Prime Minister’s country retreat, for crunch talks on a post-Brexit trade deal.
He will later head to Windsor Castle for tea with the Queen, before travelling to Scotland to play golf at his Turnberry resort.
Jeremy Corbyn said: “Theresa May has invited President Trump to our country at a time when his dangerous and inhumane policies are putting the lives and wellbeing of millions of people at risk.
“The Labour Party is committed to dialogue, including of course with those we strongly disagree with.
“In government we would find a way to work with his administration while also standing up for our values and our beliefs.
“But the Tories are rewarding President Trump with a red carpet welcome.”
Mr Corbyn also accused the US leader of “repeatedly trampling over the most basic fundamental human rights that all of us hold dear”.
He added: “He separates children from their parents and locks them up in cruel and inhumane conditions.
“He condones racism, misogyny and prejudice, and promotes the politics of hate and fear. We stand for something very, very different.
“We know that it’s only by working with our friends and allies in the United States and all over the world who want change that we can meet the huge challenges facing our planet.
“We can, we must and we will defeat the politics of division. Together we can build societies that work for the many, not the few.”
Mr Trump launched an astonishing attack on Mrs May’s Brexit plans last night, claiming the prospects of a US-UK trade deal would be dead.
The president said he would have done the Brexit negotiations “much differently” and claimed the Prime Minister did not listen to his advice.
He said: “If they do a deal like that, we would be dealing with the European Union instead of dealing with the UK, so it will probably kill the deal.
“If they do that, then their trade deal with the US will probably not be made.”
In further embarrassment to Mrs May, Mr Trump claimed that Boris Johnson has “got what it takes” to be prime minister.
He said: “I have a lot of respect for Boris. He obviously likes me, and says very good things about me.
“I was very saddened to see he was leaving government and I hope he goes back in at some point.
“I think he is a great representative for your country. I am just saying I think he would be a great Prime Minister. I think he’s got what it takes.”
