Noel Ignatiev (; December 27, 1940 – November 9, 2019) was an American author and historian.
He was best known for his work on race and social class and for his call to abolish "whiteness".
Ignatiev was the co-founder of the New Abolitionist Society and co-editor of the journal Race Traitor, which promoted the idea that "treason to whiteness is loyalty to humanity".
He also wrote a book on antebellum northern xenophobia against Irish immigrants, How the Irish Became White.
His publisher billed him as "one of America's leading and most controversial historians".
