The Baker's Dozen was a series of thirteen concerts performed by Vermont-based jam band Phish between July 21 and August 6, 2017 at Madison Square Garden in New York, New York. Each night featured a completely unique setlist with no songs repeated throughout the event, with the band playing 237 songs in total.

A jam band is a musical group whose concerts and live albums substantially feature improvisational "jamming." Typically, jam bands will play variations of pre-existing songs, extending them to improvise over chord patterns or rhythmic grooves. Jam bands are known for having a very fluid structure, playing long sets of music which often cross genre boundaries, varying their nightly setlists, and segueing from one song into another without a break.
