Fay Templeton (December 25, 1865 – October 3, 1939) was an American actress, singer, songwriter, and comedian.

Her parents were actors/vaudevillians and she followed in their footsteps, making her Broadway debut in 1900. Templeton excelled on the legitimate and vaudeville stages for more than half a century. She was a favorite headliner and heroine of popular theater, appearing until 1934. For a time she dated Sam Shubert, of the Shubert family of theatre owners, up until his death in a railroad accident.

Some of her notable performances were in H.M.S. Pinafore and Roberta. In an age of buxom beauties, she was particularly buxom, playing romantic leads despite her weight.
