Jimmy Lyons (December 1, 1931 – May 19, 1986) was an American alto saxophone player. He is best known for his long tenure in the Cecil Taylor Unit. Lyons was the only constant member of the band from the mid-1960s until his death. Taylor never worked with another musician as frequently as he did with Lyons. Lyons’ playing, influenced by Charlie Parker, kept Taylor’s avant-garde musictethered to the jazz tradition.

Lyons was born in Jersey City, New Jersey, United States, and raised there until the age of nine, when his mother moved the family to Harlem and then the Bronx. He obtained his first saxophone in the mid-1940s and took lessons from Buster Bailey
