Warner Leroy Baxter was an American film actor from the 1910s to the 1940s. Baxter is known for his role as the Cisco Kid in the 1928 film In Old Arizona, for which he won the Academy Award for Best Actor at the 2nd Academy Awards. He frequently played womanizing, charismatic Latin bandit types in Westerns, and played the Cisco Kid or a similar character throughout the 1930s, but had a range of other roles throughout his career.

The Cisco Kid is a fictional character found in numerous film, radio, television and comic book series based on the fictional Western character created by O. Henry in his 1907 short story "The Caballero's Way", published in Everybody's Magazine, v17, July 1907, as well as in the collection Heart of the West (1907). Originally a murderous criminal in O. Henry's story, the Kid was depicted as a heroic Mexican caballero later in films, radio and television adaptations.
