Lisa Goldstein (b. November 21, 1953 in Los Angeles) is a Nebula, Hugo, and World Fantasy Award nominated fantasy and science fiction writer. Her 1982 novel The Red Magician won the American Book Award for best paperback novel, and was praised by Philip K. Dick shortly before his death. Goldstein writes science fiction and fantasy; her two novels Daughter of Exile and The Divided Crown are considered literary fantasy.

Elizabeth Joy "Lisa" Goldstein's father was Heinz Jurgen "Harry" Goldstein (b. June 08, 1922 in Krefeld, Germany; d. May 24, 1974 in Los Angeles), a survivor of concentration camp Bergen-Belsen; her mother, Miriam Roth, was born in Czechoslovakia and survived the extermination camp Auschwitz. Her parents came to the United States in 1947 and met in an ESL class.

She has published two fantasy novels under the pen name Isabel Glass. She chose to use a pseudonym to separate the novels from her other work. The "Isabel" is from Point Isabel, a dog park, and "Glass" was chosen because it fits Tor's requirements for pseudonyms.

With her husband since 1986, Douglas A. "Doug" Asherman, she lives in Oakland, California.
