Christina Marie Hoff Sommers (born 1950) is an American author and philosopher. Specializing in ethics, she is a resident scholar at the American Enterprise Institute. Sommers is known for her critique of contemporary feminism. Her work includes the books Who Stole Feminism? (1994) and The War Against Boys (2000). She also hosts a video blog called The Factual Feminist.

Sommers' positions and writing have been characterized by the Stanford Encyclopedia of Philosophy as "equity feminism", a classical-liberal or libertarian feminist perspective holding that the main political role of feminism is to ensure that the right against coercive interference is not infringed. Sommers has contrasted equity feminism with what she terms victim feminism and gender feminism, arguing that modern feminist thought often contains an "irrational hostility to men" and possesses an "inability to take seriously the possibility that the sexes are equal but different". Several writers have described Sommers as anti-feminist.
