Frederick William "Freddie" Green (March 31, 1911 – March 1, 1987) was an American swing jazz guitarist. He was especially noted for his sophisticated rhythm guitar in big band settings, particularly for the Count Basie orchestra, where he was part of the "All-American Rhythm Section" with Basie on piano, Jo Jones on drums, and Walter Page on bass.
