The Adventures of Rocky and Bullwinkle and Friends (commonly referred to as simply Rocky and Bullwinkle) is an American animated television series that originally aired from November 19, 1959, to June 27, 1964, on the ABC and NBC television networks. Produced by Jay Ward Productions, the series is structured as a variety show, with the main feature being the serialized adventures of the two title characters, the anthropomorphic flying squirrel Rocket J. ("Rocky") Squirrel and moose Bullwinkle J. Moose. The main antagonists in most of their adventures are the two Russian-like spies Boris Badenov and Natasha Fatale, both working for the Nazi-like dictator Fearless Leader. Supporting segments include "Dudley Do-Right" (a parody of old-time melodrama), "Peabody's Improbable History" (a dog named Mr. Peabody and his boy Sherman traveling through time), and "Fractured Fairy Tales" (classic fairy tales retold in comic fashion), among others. The current blanket title was imposed for home video releases more than 40 years after the series originally aired and was never used when the show was televised; television airings of the show were broadcast under the titles of Rocky and His Friends from 1959 to 1961 on Tuesday and Thursday afternoons on ABC (and again in Canada in 1963), The Bullwinkle Show from 1961 to 1964 on Sunday evening and then late Sunday afternoon on NBC, and The Rocky and Bullwinkle Show (or The Adventures of Rocky and Bullwinkle) as repeats from 1964-73 on Sunday mornings on ABC and in syndication following this.

Rocky and 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. It was also one of the first cartoons whose animation was outsourced; storyboards were shipped to Gamma Productions, a Mexican studio also employed by Total Television. The art has a choppy, unpolished look and the animation is extremely limited even by television animation standards at the time, yet the series has long been held in high esteem by those who have seen it; some critics described the series as a well-written radio program with pictures.

The show was shuffled around several times during its run, airing in afternoon, prime time, and Saturday-morning cartoon timeslots, and was influential to other animated series from The Simpsons to Rocko's Modern Life. Segments from the series were later recycled in the Hoppity Hooper show. There have been numerous feature film adaptations of the series' various segments, such as the 2000 film The Adventures of Rocky and Bullwinkle, which blended live-action and computer animation; and the 1999 live-action film Dudley Do-Right. Both films received poor reviews and were financially unsuccessful. By contrast, an animated feature film adaptation of the "Peabody's Improbable History" segment, Mr. Peabody & Sherman, was released to positive reviews in 2014, but was also financially unsuccessful. A rebooted animated series also based on "Peabody's Improbable History", The Mr. Peabody & Sherman Show, debuted on Netflix in October 2015 and ran to April 2017.

Another reboot animated series based on the main and final segments, The Adventures of Rocky and Bullwinkle premiered on Amazon Prime Video on May 11, 2018. In 2013, Rocky and His Friends and The Bullwinkle Show were ranked the sixth-greatest television cartoon of all time by TV Guide.
