Oscar Frederic Moore (December 25, 1916 – October 8, 1981) was an American jazz guitarist with the Nat King Cole Trio.

The son of a blacksmith, Moore was born in Austin, Texas, United States. The Moore family moved to Phoenix, Arizona, where he began performing with his older brother Johnny, who played both trombone and guitar. After moving to Los Angeles, he participated in his first recording session for Decca as part of the Jones Boys Sing Band led and arranged by Leon René. The group attracted local attention on radio and in two short films for MGM directed by Buster Keaton. Soon after, Moore accompanied pianist Nat King Cole at the Swanee Inn in North La Brea, Hollywood. He spent ten years with Cole in the piano-guitar-bass trio format, that influenced Art Tatum, Oscar Peterson, Ahmad Jamal.
