Germaine Greer (born 29 January 1939) is an Australian-born writer, academic, journalist and scholar of early modern English literature, widely regarded as one of the most significant feminist voices of the later 20th century.

Greer's ideas have created controversy ever since her book The Female Eunuch became an international best-seller in 1970, turning her into a household name and bringing her both adulation and opposition. She is also the author of many other books including, Sex and Destiny: The Politics of Human Fertility (1984); The Change: Women, Ageing and the Menopause (1991) and Shakespeare's Wife (2007). She currently serves as Professor Emeritus of English Literature and Comparative Studies at the University of Warwick.

Greer was born in Melbourne in 1939, growing up in the bayside suburb of Mentone. Her father was a leading Australian insurance executive, who served as a Wing Commander in the wartime RAAF. After attending a private convent school, Star of the Sea College, in Gardenvale, she won a teaching scholarship in 1956 and enrolled at the University of Melbourne. After graduating with a degree in English and French language and literature, she moved to Sydney, where she became involved with the Sydney Push social milieu and the anarchist Sydney Libertarians at its centre. Christine Wallace, in her unauthorised biography, describes Greer at this time:
