Judy Holliday (born Judith Tuvim, June 21, 1921 – June 7, 1965) was an American actress, comedian, and singer.

She began her career as part of a nightclub act before working in Broadway plays and musicals. Her success as Billie Dawn in the 1946 stage production of Born Yesterday led to her being cast in the 1950 film version for which she won an Academy Award for Best Actress and a Golden Globe Award for Best Actress – Motion Picture Musical or Comedy. She was known for her performance on Broadway in the musical Bells Are Ringing, winning a Tony Award for Best Performance by a Leading Actress in a Musical and reprising her role in the 1960 film adaptation.

In 1952, Holliday was called to testify before the Senate Internal Security Subcommittee to answer claims she was associated with communism. Unlike other figures who lost standing, Holliday managed to get through unscathed. She continued to act on Broadway and film until her death from breast cancer in 1965.
