He-Gassen (Japanese: 屁合戦, literally: "Fart competitions"), or Houhi-Gassen (放屁合戦), are titles given to a Japanese art scroll, created during the Edo period (1603–1868) by an unknown artist or several unknown artists depicting flatulence humor.
He-Gassen is a subject occasionally depicted in Japanese art, first attested at the end of the Heian Period (794–1185). Toba Sōjō (1053–1140), in addition to his famous Scrolls of Frolicking Animals, is also mentioned as having painted scrolls on themes such as "Phallic Contest" and "He-gassen."
