Urban Clifford “Urbie” Green (born August 8, 1926) is an American jazz trombonist who toured with Woody Herman, Gene Krupa, Jan Savitt, and Frankie Carle.

He has played on over 250 recordings and has released more than two dozen albums as a soloist and is highly respected by his fellow trombonists. Green’s trombone sound is especially noted for its warm, mellow tone, even in the higher registers where he is more fluent than most trombonists. His technique is considered flawless by many in the music industry and has appeared in major jazz festivals, motion pictures, concert halls, nightclubs, radio, television and the White House. He was inducted into the Alabama Jazz Hall of Fame in 1995.

Born in Mobile, Alabama, Green was taught the piano as a child by his mother, jazz and popular tunes from the beginning. He picked up the trombone, which both older brothers played, when he was about 12. Although he listened to such trombone greats as Tommy Dorsey, J. C. Higginbotham, Jack Jenney, Jack Teagarden and Trummy Young he has said that he was more influenced by the styles of Dizzy Gillespie, Charlie Parker, and Lester Young. Urbie’s trombone style was also influenced by vocalists such as Perry Como, and the vocal style of Louis Armstrong.
