David Spencer Ware (November 7, 1949 – October 18, 2012) was an American jazz saxophonist, composer, and bandleader.

Ware was born in Plainfield, New Jersey, grew up in Scotch Plains, New Jersey, graduated from Scotch Plains-Fanwood High School, and briefly attended the Berklee College of Music. He moved to NYC in 1973, where he participated in the loft jazz scene, and later worked as a cab driver for 14 years in order to focus on his own group concept. In the early 1980s, he returned to Scotch Plains with his wife Setsuko S. Ware.

Ware’s debut album as a leader was recorded in 1977 – together with pianist Gene Ashton (aka Cooper-Moore) and drummer Marc Edwards – and released by HatHut in 1979. He performed and recorded with the groups of pianist Cecil Taylor and drummer Andrew Cyrille in the mid-late 1970s. He formed his own quartet in 1989. The group was originally composed of Ware, pianist Matthew Shipp, bassist William Parker, and drummer Marc Edwards. While Shipp and Parker were members for the group’s entire existence, the drum chair was later occupied by Whit Dickey, Susie Ibarra, and Guillermo E. Brown.
