James Edward Heath (October 25, 1926 – January 19, 2020), nicknamed Little Bird, was an American jazz saxophonist, composer, arranger, and big band leader. He was the brother of bassist Percy Heath and drummer Albert Heath.

Heath was born in Philadelphia on October 25, 1926. His father, an auto mechanic, played the clarinet, performing on the weekends. His mother sang in a church choir. The family frequently played recordings of big band jazz groups around the house. Heath's sister was a pianist, while his brothers were bassist Percy Heath (older) and drummer Albert Heath (his youngest sibling).

During World War II, Heath was rejected for the draft for being below the minimum weight.

Heath originally played alto saxophone. He earned the nickname "Little Bird" after his work for Howard McGhee and Dizzy Gillespie in the late 1940s, during which his playing displayed influences from Charlie Parker (Parker's nickname was "Bird"). He then switched to tenor saxophone.

From late 1945 through most of 1946, he performed with the Nat Towles band. In 1946, he formed his own band, which was a fixture on the Philadelphia jazz scene until 1949. The band included John Coltrane, Benny Golson, Specs Wright, Cal Massey, Johnny Coles, Ray Bryant, and Nelson Boyd. Charlie Parker and Max Roach sat in on one occasion. The band performed at venues such as the Apollo Theater in Harlem. Although Heath recalls that the band recorded a few demos on acetate, it never released any recordings, and its arrangements were lost at a Chicago train station. The band dissolved in 1949 so that Heath could join Dizzy Gillespie's band.
