John Henry is the fifth studio album by American alternative rock group They Might Be Giants. It was released in 1994. It is the first album by They Might Be Giants to include a full band arrangement, rather than synthesized and programmed backing tracks. The album's name, a reference to the man versus machine fable of John Henry, is an allusion to the band's fundamental switch to more conventional instrumentation, especially the newly established use of a human drummer instead of a drum machine.

They Might Be Giants, often abbreviated as TMBG, is an American alternative rock band formed in 1982 by John Flansburgh and John Linnell. During TMBG's early years, Flansburgh and Linnell frequently performed as a musical duo, often accompanied by a drum machine. In the early 1990s, TMBG expanded to include a backing band. The duo's current backing band consists of Marty Beller, Dan Miller and Danny Weinkauf. They have been credited as vital in the creation and growth of the prolific DIY music scene in Brooklyn in the mid-1980s.
