McCoy Tyner (born December 11, 1938, Philadelphia, Pennsylvania, U.S.—died March 6, 2020, New Jersey) was an American jazz pianist, bandleader, and composer, noted for his technical virtuosity and dazzling improvisations.

Tyner began performing with local jazz ensembles while in his mid-teens. He met saxophonist John Coltrane in 1955 and, after a brief stint (1959) with a group led by Art Farmer and Benny Golson, helped Coltrane form his renowned quartet in 1960. Tyner developed his signature strong pentatonic chord-playing style and lightning-fast runs during his years with Coltrane. In addition, the group began incorporating elements of African and other musical genres into their playing style.

Striking out on his own in 1965, Tyner led a variety of ensembles (for many years including bassist Ron Carter) and also worked solo and extensively as a sideman. From the mid-1980s he performed largely in a trio, but he also formed a big band that made occasional appearances. Tyner made dozens of recordings in his own name and contributed to dozens more. Notable among his own albums are The Real McCoy (1967), Sahara (1972), 4 × 4 (1980), and Infinity (1995) and, with his big band, Uptown/Downtown (1988). Tyner converted to Islam in the mid-1950s and adopted the name Sulaimon Saud.
