Bill Harris (October 28, 1916 – August 21, 1973) was a jazz trombonist.
Early in his career, Harris performed with Benny Goodman, Charlie Barnet, and Eddie Condon. He is renowned for his broad, thick tone and quick vibrato that remained for the duration of each tone. He went on to join Woody Herman's First Herd in 1944. He was also in the Four Brothers Second Herd during the late 1940s, and he worked with Herman again in the 1950s. He then teamed up with Charlie Ventura and later with Chubby Jackson. Together with Flip Phillips, he became a stalwart of Benny Goodman's group in 1959. Later, Harris worked in Las Vegas, finally retiring to Florida.
