Bosko the Doughboy is a one-reel animated cartoon short subject, part of the Bosko series. It was directed by Hugh Harman, and first released on October 17, 1931 as part of the Looney Tunes series from the Leon Schlesinger animation studio and distributed by Warner Brothers. The cartoon is usually considered one of the better Hugh Harman Bosko cartoons.

The cartoon opens with images of explosions, gunfire, and heavy artillery; one character even fires into the camera. It is World War I, and the ever-cheerful Bosko is eating down in a trench. Enemy fire destroys his meal, and later a picture of his girlfriend, Honey. Bosko shows a rare moment of anger, but is quickly cheered up by a fellow soldier. The two begin to dance, only to be interrupted by more gunfire. Bosko finally decides to fight back and downs an enemy bomber (actually a pelican) by using a fellow soldier as a cannon. A friendly hippopotamus is shot down by heavy artillery, which Bosko destroys with a pair of longjohns-turned-catapult. He then saves the wounded soldier by unzipping his navel and retrieving the shell inside. The projectile explodes anyway, turning the already black-faced Bosko even blacker and prompting him to exclaim "Mammy!" à la Al Jolson.

Bosko the Doughboy is notable for its departure from the standard cartoon formula of its era. Bosko is usually infallibly happy and chipper; Doughboy forces him to drop this demeanor and fight back. Other Bosko shorts concentrate primarily on Bosko cavorting with other characters in a musical wonderland; in Doughboy, Bosko can't dance more than a few seconds before coming under enemy fire. Bosko's cartoons generally have little to no conflict; Doughboy is nothing but fighting. In short, Bosko the Doughboy is almost a total departure from other shorts in the series (and from those of other studios of the time). It is usually regarded as a high point of the character's cartoon career.
