Marc Daubert was the percussionist for the rock band Phish for a brief time in their early history, joining the band in September 1984 and leaving the band in February 1985.

Daubert was a close friend of guitarist Trey Anastasio, who was suspended from the University of Vermont in the spring of 1984. During his suspension, Phish went on temporary hiatus as Anastasio, Daubert, and lyricist/keyboardist Tom Marshall recorded a project entitled Bivouac Jaun. Much of this recording would end up on Phish's debut album, known as The White Tape.

When Anastasio returned to UVM in September 1984, he brought Daubert along and Phish officially hired him as percussionist. The most circulated Phish tape featuring Daubert is from a performance on December 1, 1984, at the legendary club Nectar's in downtown Burlington, Vermont. After a run of shows in February 1985 at a club called Doolin's, Daubert quit the band.

Daubert also penned the lyrics to the Phish song "The Curtain," which was first performed live by Phish in 1987, over two years after Daubert's departure from the band.
