William John Scott was an American voice actor, writer and producer for animated cartoons, primarily associated with Jay Ward and UPA, as well as one of the founding members of ASIFA-Hollywood. He is probably best known as the head writer, co-producer and the voice of several characters from the popular programs Rocky and His Friends and The Bullwinkle Show.

The Adventures of Rocky and Bullwinkle and Friends 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", "Peabody's Improbable History", and "Fractured Fairy Tales", 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, The Bullwinkle Show from 1961 to 1964, and The Rocky and Bullwinkle Show in syndication.
