Ronald 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 other jazz musicians. Among the musicians Ball performed with are Chuck Wayne (1952), Dizzy Gillespie, Lee Konitz (1953–55), Kenny Clarke, Hank Mobley, Art Pepper, J.J.
