Jack Donovan is an American far-right writer and activist. A self-described masculinist, Donovan was an influential figure in the alt-right until he disavowed the movement in 2017. He has at various times advocated male supremacy, white nationalism, fascism, and the political disenfranchisement of women. He led a chapter of the Wolves of Vinland, a Norse neopagan organization and SPLC-designated hate group, from 2014 to 2018.
