Claudette Colbert ( kohl-BAIR; born Émilie Claudette Chauchoin; September 13, 1903 – July 30, 1996) was an American actress. Colbert began her career in Broadway productions during the late 1920s and progressed to motion pictures with the advent of talking pictures. Initially associated with Paramount Pictures, she gradually shifted to working as a freelance actress. She won the Academy Award for Best Actress in It Happened One Night (1934), and received two other Academy Award nominations. Her other notable films include Cleopatra (1934) and The Palm Beach Story (1942).

With her round face, big eyes, charming, aristocratic manner, and flair for light comedy and emotional drama, Colbert's versatility led to her becoming one of the best-paid stars of the 1930s and 1940s and, in 1938 and 1942, the highest-paid. She starred in more than 60 movies. Among her frequent co-stars were Fred MacMurray, in seven films (1935–1949), and Fredric March, in four films (1930–1933).

By the early 1950s, Colbert had turned from the screen to television and stage work, and she earned a Tony Award nomination for The Marriage-Go-Round in 1959. Her career tapered off in the early 1960s, but in the late 1970s, it experienced a resurgence in theater, and she received a Sarah Siddons Award for her Chicago theater work in 1980. For her television work in The Two Mrs. Grenvilles (1987), she won a Golden Globe Award and received an Emmy Award nomination.

In 1999, the American Film Institute named Colbert the 12th-greatest female star of classic Hollywood cinema.
