Oscar Frederic Moore (December 25, 1916 – October 8, 1981) was an influential American jazz guitarist best known for his work with the Nat King Cole Trio. Born in Austin, Texas, Moore was the son of a blacksmith and moved with his family to Phoenix, Arizona, where he began performing with his older brother Johnny. The family later relocated to Los Angeles, where Moore participated in his first recording session with the Jones Boys Sing Band.

Moore gained significant recognition as a member of the Nat King Cole Trio, where he played guitar in a piano-guitar-bass format that left a lasting impact on jazz musicians such as Art Tatum, Oscar Peterson, and Ahmad Jamal. Moore's exceptional talent earned him top placements in polls by DownBeat, Metronome, and Esquire magazines between 1943 and 1948. His work with the trio was highly regarded, with Art Tatum expressing admiration for Moore in a 1944 interview.

After leaving the King Cole Trio in 1947 due to financial disagreements, Moore joined Johnny Moore's Three Blazers and later formed his own trio in 1952. He continued to perform and record in Los Angeles throughout the 1950s, both as a leader and a sideman. Despite leaving the music industry at the end of the decade, Moore returned to the studio in 1965 to record a tribute to Nat King Cole. He briefly collaborated with Helen Humes in the 1970s before passing away from a heart attack in Clark, Nevada, in 1981.
