The Women's National Abortion Action Coalition (WONAAC) was a feminist coalition in the United States, formed in 1971 to campaign for the legalization of abortion and to defend reproductive rights.
WONAAC organized demonstrations conferences and lobbying campaigns across major U.S. cities in the early 1970s. It brought together members of the women's liberation movement, trade union activists, students and health care workers to demand the repeal of restrictive abortion laws.
