Sheila Jeffreys, English-Australian political scientist, author, and academic
Sheila Jeffreys (born 13 May 1948) is a former professor of political science at the University of Melbourne, born in England. A lesbian feminist scholar, she analyses the history and politics of human sexuality.

Jeffreys' argument that the "sexual revolution" on men's terms contributed less to women's freedom than to their continued oppression has both commanded respect and attracted intense criticism. She argues that women suffering pain in pursuit of beauty is a form of submission to patriarchal sadism, that transsexuals reproduce oppressive gender roles and mutilate their bodies through sex reassignment surgery, and that lesbian culture has been negatively affected by emulating the sexist influence of the gay male subculture of dominant/submissive sexuality.

She is the author of several books about feminism and feminist history, including The Spinster and Her Enemies (1985), The Sexuality Debates (1987), Anticlimax (1990), Unpacking Queer Politics (2003), Beauty and Misogyny (2005), and Gender Hurts (2014).
