Tracy Scoggins (b. November 13, 1953 in Dickinson, Texas) is an American actress. She is perhaps best known for her roles as Cat Grant in the television series Lois & Clark: The New Adventures of Superman and Monica Colby in the popular 1980s prime time soap opera Dynasty, and its spin-off series The Colbys. However, fans of the Babylon 5 TV series remember her as Captain Elizabeth Lochley, the station's competent yet troubled commander during the final season.
