Urban Clifford "Urbie" Green (August 8, 1926 – December 31, 2018) was an American jazz trombonist who toured with Woody Herman, Gene Krupa, Jan Savitt, and Frankie Carle. He played on over 250 recordings and released more than two dozen albums as a soloist, and was highly respected by his fellow trombonists. Green's trombone sound was especially noted for its warm, mellow tone, even in the higher registers where he was more fluent than most trombonists.
