BET J (previously known as BET on Jazz and later BET Jazz) is a spin-off cable television channel of BET (Black Entertainment Television), created originally to showcase jazz music-related programming, especially that of black jazz musicians.

BET on Jazz later became BET Jazz. On March 1, 2006, the network re-branded again, this time as BET J. While jazz music still remains the stated primary focus, programming has been expanded to include a block of Caribbean programs as well as some R&B, neo soul, and alternative hip hop. To a lesser extent, BET J also focuses on go-go, electronica, and alternative rock.

BET J is available in 28 million homes on DirecTV, Verizon FiOS TV as well as other digital cable providers. Programs include My Two Cents with Keith Boykin, Bryonn Bain, Crystal McCreary Anthony and Staceyann Chin, The Best Shorts hosted by Abiola Abrams, Living the Life of Marley about Ky-Mani Marley, My Model is Better Than Your Model with Eva Pigford and The Turn On hosted by Charlotte Burley.
