Mr Wilders also addressed the US Republican Party National Convention in Cleveland, Ohio, last month. Mr Trump's campaign has been marked by hardline rhetoric on immigration and social issues.
Mr Hussein, the UN High Commissioner for Human Rights, told the inauguration of the Peace, Justice and Security Foundation, that he wanted to address his statement to "Geert Wilders, his acolytes, indeed to all those like him - the populists, demagogues and political fantasists".
"I am a Muslim, who is, confusingly to racists, also white-skinned; whose mother is European and father, Arab. And I am angry, too, because of Mr Wilders' lies and half-truths, manipulations and peddling of fear," Mr Hussein said.
He described the PVV manifesto as "grotesque" and said Mr Wilders had much in common with presidential hopeful Donald Trump, Hungary's Prime Minister Viktor Orban, France's National Front leader Marine Le Pen, and former UKIP party leader Nigel Farage.
He said all had similarities to the ideology espoused by the Islamic State (IS) group. "All seek in varying degrees to recover a past, halcyon and so pure in form, where sunlit fields are settled by peoples united by ethnicity or religion. A past that most certainly, in reality, did not exist anywhere, ever."
He added: "Make no mistake, I certainly do not equate the actions of nationalist demagogues with those of Daesh (IS). But in its mode of communication, its use of half-truths and oversimplification, the propaganda of Daesh uses tactics similar to those of the populists."
