Lisa Hartman (born June 1, 1956 in Houston, Texas) is an American actress and singer.
After some minor television appearances, Lisa Hartman starred in the short-lived Bewitched spin-off, Tabitha during 1977-78. She subsequently appeared frequently on television in guest roles, and appeared in the 1981 CBS TV remake of Jacqueline Susann's Valley of the Dolls, as Neely O'Hara.
She then played a major role in the primetime soap Knots Landing, as rock singer Ciji Dunne, during 1982 and 1983. When her television character was murdered, reaction from fans prompted the producers to create a new "look-alike" character for Hartman. She remained with the show until 1986. She then continued to appear in television guest roles, and played the lead in the feature film Where the Boys Are '84.
