"Uncle John's Band" is a song by the Grateful Dead that first appeared in their concert setlists in late 1969. The band recorded it for their 1970 album Workingman's Dead. Written by guitarist Jerry Garcia and lyricist Robert Hunter, "Uncle John's Band" presents the Dead in an acoustic and musically concise mode, with close harmony singing.

Workingman's Dead is the fourth studio album by American rock band Grateful Dead. It was recorded in February 1970 and originally released on June 14, 1970. The album and its studio follow-up, American Beauty, were recorded back-to-back using a similar style, eschewing the psychedelic experimentation of previous albums in favor of Jerry Garcia and Robert Hunter's Americana-styled songcraft.
