One Droopy Knight is a 1957 animated short subject in the Droopy series,[5] directed by Michael Lah and produced by William Hanna and Joseph Barbera for Metro-Goldwyn-Mayer in CinemaScope.

[4] Essentially a remake of 1949's Señor Droopy, but taking place in a medieval setting rather than the country of Mexico, One Droopy Knight casts Droopy and his rival Butch as medieval knights out to slay a dragon and win the hand of a beautiful human princess.

Droopy's attacks are harmless, and receives little harm in return when the dragon evicts him.

The camera pulls back from the scene of the fleeing dragon to show that it is framed within a book.

It was nominated for an Academy Award for Best Animated Short Film in 1958,[4] but lost to Birds Anonymous, a Sylvester & Tweety cartoon from Warner Bros.[6][7]
