Judy Rae Grahn (born July 28, 1940, in Chicago) is an American poet. She is openly lesbian and has written many lesbian feminist works.

Grahn was a member of the Gay Women's Liberation Group, the first lesbian feminist collective on the west coast, founded around 1969. The collective established A Woman's Place, the first women's bookstore, and The Women's Press Collective, the first all-woman publisher.

Grahn's poetry collections include: Edward the Dyke and Other Poems (1971), A Woman is Talking to Death (1974), She Who (1977), The Queen of Wands (1982), The Work of a Common Woman: Collected Poetry (1964-1977) (1984). Other publications include: Another Mother Tongue (1990, on the history of lesbian and gay culture) and Blood, Bread, and Roses: How Menstruation Created the World (1994).

In 1997, Publishing Triangle, an association of lesbians and gay men in publishing, established the Judy Grahn award to recognize the best nonfiction book of the year affecting lesbian lives.

Grahn is the co-director of the Women's Spirituality MA program and Program Director of the MFA in Creative Inquiry at the New College of California. She also initiated and edits the online academic journal Metaformia.
