Gary Crosby OBE (born 26 January 1955) is a British jazz double bassist, composer, music arranger, and educator.

[6][7] Crosby started out playing trumpet but in his teens studied with noted bassist Peter Ind, going on to become a founding member in 1986 of the Jazz Warriors[8] – a group that showcased such talented young Black musicians as Courtney Pine, Steve Williamson, Cleveland Watkiss, Phillip Bent, and Orphy Robinson.

In 1991, Crosby established Tomorrow's Warriors, providing a platform for talented young musicians who wished to pursue a career in jazz.

Tomorrow's Warriors continues to develop the careers of young musicians and with core programmes and workshops at Southbank Centre, London.
