Nancy Ann Olson (born July 14, 1928) is an American actress. She received an Academy Award nomination for Best Supporting Actress, for her portrayal of Betty Schaefer in Sunset Boulevard (1950). Since the early 1980s, Olson has been virtually retired from acting, although she has made a few rare returns, most recently in 2012. Olson was signed to a film contract by Paramount Pictures in 1948 and, after a few supporting roles, producers began to consider her for more prominent parts. She was up for the role of Delilah in Cecil B. DeMille's 1949 film Samson and Delilah, for which Olson later said she was not suited. When she was passed over in favor of Hedy Lamarr, Billy Wilder cast her for his upcoming project.
