Harold Mabern Jr. (March 20, 1936 – September 17, 2019) was an American jazz pianist and composer, principally in the hard bop, post-bop, and soul jazz fields. He is described in The Penguin Guide to Jazz Recordings as “one of the great post-bop pianists”.

Mabern was born in Memphis, Tennessee on March 20, 1936. He initially started learning drums before switching to learning piano. He had access to a piano from his teens, after his father, who worked in a lumber yard, saved to buy him one. Mabern learned by watching and emulating pianists Charles Thomas and Phineas Newborn Jr.
