Jeffrey David "J.D." Pinkus (born October 26, 1967) is an American bassist best known for his work with Butthole Surfers from 1985 to 1994 and since their 2009 reunion.
In 1990, he and Butthole Surfers' lead vocalist Gibby Haynes released Digital Dump, the only album from their psychedelic house music side project The Jackofficers.
Upon leaving Butthole Surfers, Pinkus worked full-time with the Austin trio Daddy Longhead, which he had assembled during his waning months in the band, and which included longtime Atlanta associate Jimbo Young on guitar and Rey Washam on drums.
