Grace Patricia Kelly (November 12, 1929 – September 14, 1982) was an American film actress who became Princess of Monaco after marrying Prince Rainier III in April 1956.

After embarking on an acting career in 1950, when she was 20, Kelly appeared in New York City theatrical productions and more than 40 episodes of live drama productions broadcast during the early 1950s Golden Age of Television. In October 1953, she gained stardom from her performance in director John Ford's film Mogambo starring Clark Gable and Ava Gardner, which won her a Golden Globe Award and an Academy Award nomination in 1954.

Kelly retired from acting at the age of 26 to marry Rainier, and began her duties as Princess of Monaco. They had three children: Caroline, Albert, and Stéphanie. Kelly retained her link to America by her dual U.S. and Monégasque citizenship. Princess Grace died at Monaco Hospital on September 14, 1982, succumbing to injuries sustained in a traffic collision the day before.

She is listed 13th among the American Film Institute's 25 Greatest Female Stars of Classical Hollywood Cinema.
