Marilyn Hacker (born 1942, New York City) is an American poet and translator widely regarded as one of the foremost practitioners of formal verse in contemporary American poetry. She is the author of more than a dozen collections including Presentation Piece (1974), which won the National Book Award; Love, Death, and the Changing of the Seasons (1986); Winter Numbers (1994); and A Stranger's Mirror: New and Selected Poems 1994–2014 (Norton, 2015). Her work demonstrates that traditional forms — sonnets, villanelles, ghazals — can be powerful vehicles for feminist and erotic consciousness. She has received the Lenore Marshall Prize, the Robert Frost Medal, and a Guggenheim Fellowship, and is also a prolific translator of contemporary French-language poetry.
