David Gregory Bliss (born September 20, 1943) is an American basketball coach. He served as the head men's basketball coach at Oklahoma, Southern Methodist, New Mexico, and Baylor of the NCAA Division I, as well as Southwestern Christian of the NAIA.

Bliss resigned from Baylor in 2003 following internal and NCAA investigations into a number of circumstances surrounding the murder of Baylor player Patrick Dennehy by teammate Carlton Dotson. These included the alleged involvement of Bliss in making illicit tuition payments for players Dennehy and Corey Herring, and his attempt to frame Dennehy posthumously as a drug dealer in order to provide cover for himself; in 2005, the NCAA issued Bliss a 10-year "show-cause" notice.
