Donald Jess "Don" Bachardy (born May 18, 1934) is an American portrait artist. He resides in Santa Monica, California.
Born in Los Angeles, California, Bachardy was the life partner of writer Christopher Isherwood, whom he met on Valentine's Day 1953, when he was 18 and Isherwood was 48. They remained together until Isherwood's death in 1986. A number of paperback editions of Isherwood's novels feature Bachardy's pencil portraits of the author. A film about their relationship, titled Chris & Don: A Love Story, was released in 2008.
Bachardy studied at the Chouinard Art Institute in Los Angeles and the Slade School of Art in London. His first one-man exhibition was held in October 1961 at the Redfern Gallery in London.
