Bullwinkle J. Moose is a fictional character in the 1959-1964 animated television series Rocky and His Friends and The Bullwinkle Show, often collectively referred to as Rocky and Bullwinkle, produced by Jay Ward and Bill Scott. Bullwinkle was noted for being well-meaning, but also quite dim-witted, which made for a source of jokes during the show's run. Despite this, the so-called "moronic moose" often aided the brains of the "moose-and-squirrel" duo, Rocky, during their various adventures. Although on opposite ends of the I.Q. scale, he and the "plucky squirrel" had a shared sense of optimism, persistence and traditional ethics and moral standards.

The anthropomorphic moose Bullwinkle and flying squirrel Rocky. The main adversaries in most of their adventures are the Russian-like spies Boris Badenov and Natasha Fatale. Supporting segments include Dudley Do-Right (a parody of old-time melodrama), Peabody's Improbable History (a dog and his pet boy Sherman traveling through time), and Fractured Fairy Tales (classic fairy tales retold in comic fashion), among others. Rocky & Bullwinkle is known for quality writing and wry humor. Mixing puns, cultural and topical satire, and self-referential humor, it appealed to adults as well as children.
