​Brenda Marshall (September 29, 1915 – July 30, 1992) was an American film actress.

Born Ardis Ankerson in Negros, Philippines, Marshall made her first film appearance in the 1939 Espionage Agent. The following year, she played the leading lady to Errol Flynn in The Sea Hawk. After divorcing actor Richard Gaines in 1940, she married the actor William Holden in 1941 and her own career quickly slowed. She starred opposite James Cagney in the 1942 film Captains of the Clouds. The Constant Nymph (1943) was a popular success but she virtually retired after this, appearing in only four more inconsequential films. Among these, she played scientist Nora Goodrich in the grade-B 1946 cult classic Strange Impersonation.
