American comedian famous on the vaudeville circuit in the late 19th and early 20th century.

As a child he sang and danced in the streets of New York and Chicago to help support his family. He gained his first professional recognition in the mining camps and cow towns of the West, beginning around 1878. He returned to Chicago in 1888 as the star comedian in variety shows and revues. Between 1904 and 1913 he played the leading comic roles in a series of musical comedies in New York City, among them Piff! Paff! Pouf! and The Earl and the Girl. He entered vaudeville in 1913 with a highly successful act that included his seven children and appeared with them in one motion picture. Foy retired in 1923 but returned to the stage in 1927 and died while on a farewell tour. Alvin F. Harlow coauthored Foy's autobiography, Clowning Through Life (1928). Eddie Foy, Jr. (1905–83), Foy's son, was active in vaudeville, films, the musical and legitimate stage, and television.
