Molly Keane (1904-1996) was an Irish novelist and playwright. She grew up at Ballyrankin in County Wexford and was educated at a boarding school in Bray, County Wicklow. She married Bobby Keane, one of a Waterford squirearchical family in 1938 and had two daughters.

She used her married name for her later novels, several of which (Good Behaviour, Time After Time) have been adapted for television. Between 1928 and 1956, she wrote eleven novels, and some of her earlier plays, under the pseudonym M. J. Farrell. Her husband died suddenly in 1946, and following the failure of a play she published nothing for twenty years. In 1981, Good Behaviour came out under her own name. The novel was warmly received and was shortlisted for the Man Booker Prize.
