Ronald “Ronnie” Ball (December 22, 1927 – October 1984) was a jazz pianist, composer and arranger, born in Birmingham, England.

Ball moved to London in 1948, and in the early 1950s he worked both as a bandleader and under Ronnie Scott, Tony Kinsey, Victor Feldman, and Harry Klein. In 1952 he moved to New York City and studied with Lennie Tristano. At the time it was his ambition to learn more about the American jazz scene and in the 1950s and 1960s he worked extensively with well-known jazz personnel. Among the musicians Ball played with are Chuck Wayne (1952), Dizzy Gillespie, Lee Konitz (1953–55), Kenny Clarke, Hank Mobley, Art Pepper, J.J.
