Eugene Curran Kelly (August 23, 1912 – February 2, 1996) was an American actor, dancer, singer, filmmaker, and choreographer. He was known for his energetic and athletic dancing style, his good looks, and the likable characters that he played on screen. He starred in, choreographed, or co-directed some of the most well-regarded musical films of the 1940s and 1950s, until they fell out of fashion in the late 1950s.

Kelly is best known today for his performances in films such as Cover Girl (1944), Anchors Aweigh (1945), for which he was nominated for an Academy Award for Best Actor, On the Town (1949), which was his directorial debut, An American in Paris (1951), Singin' in the Rain (1952), Brigadoon (1954), and It's Always Fair Weather (1955).

After musicals he starred in two films outside the musical genre: Inherit the Wind (1960) and What a Way to Go! (1964). In 1967, he appeared in French director Jacques Demy's musical comedy The Young Girls of Rochefort opposite Catherine Deneuve. Kelly solo directed the comedy A Guide for the Married Man (1967) starring Walter Matthau, and later the extravagant musical Hello, Dolly! (1969) starring Barbra Streisand, recognized with an Oscar nomination for Best Picture. Kelly co-hosted and appeared in Ziegfeld Follies (1946), That's Entertainment!
