Mieczysław Munz (October 31, 1900, Kraków – August 25, 1976) was a Polish-American pianist.
Munz trained in Vienna and Berlin, with Ferruccio Busoni. He was a teacher of Emanuel Ax, Walter Hautzig, David Oei, Ann Schein, Virginia Reinecke and Adolovni Acosta.
He left concertizing in the early 1940s after developing physical problems with his right hand.
His ex-wife was Aniela (Nela) Młynarska (daughter of Emil Młynarski), who later married Arthur Rubinstein.
