Oscar Moore (December 25, 1916 – October 8, 1981) was an American swing jazz guitarist. Moore was an integral part of the Nat King Cole Trio during 1937–1947, appearing on virtually all of Cole's records during the period. A superb and influential guitarist, Moore was himself influenced by Charlie Christian. Barney Kessel once said that Moore practically created the role of the jazz guitarist in small combos. He also recorded with Lionel Hampton, Art Tatum (1941), the Capitol Jazzmen, and Lester Young.
