Grace Patricia Kelly (November 12, 1929—September 14, 1982) was an American actress who, in April 1956, married Rainier III, Prince of Monaco. She assumed the title of Her Serene Highness, the Princess of Monaco, and was commonly referred to as Princess Grace.

After embarking on an acting career in 1948, at the age of 18, Grace Kelly appeared in New York City theatrical productions as well as more than 40 live broadcasts during the early 1950s Golden Age of Television. In 1954, she became a movie star with the release of five films, one of which, The Country Girl, provided her with an Academy Award-winning role as Best Actress. Retiring from acting at 26 and entering upon her duties in Monaco, she and Prince Rainier became the parents of three children: Caroline, Albert, and Stephanie. She also retained her American roots, maintaining a dual U.S. and Monegasque citizenship. Her death, two months before her 53rd birthday, was the result of an automobile accident. In June 1999, the American Film Institute ranked her #13 amongst the Greatest Female Stars of All Time.
