Paul Horace Plimley (16 March 1953 – 18 May 2022) was a free jazz pianist and vibraphonist. He was one of the doyens of the Canadian jazz avant-garde, a co-founder of the New Orchestra Workshop Society and frequent collaborator with the bassist Lisle Ellis. He was well-versed in classical music and in all styles of jazz; he was one of the first and most convincing interpreters of Ornette Coleman's music on the piano (an instrument usually seen as antithetical to Coleman's music). Plimley died in Vancouver at the age of 69 on 18 May 2022 from cancer.
