Mel Blanc provided the original voice for Bugs Bunny and continued voicing the character for decades.

Britannica identifies Mel Blanc as the voice artist who gave Bugs Bunny his famous voice, and the Wikipedia list of Bugs Bunny cartoons confirms that Blanc voiced the character throughout the golden age of animation. Blanc's range was extraordinary — he voiced nearly every Looney Tunes character — but Bugs Bunny's laid-back, confident delivery became one of the most recognizable vocal performances in film history. Later voice actors including Jeff Bergman, Billy West, and Eric Bauza have carried the role into new eras.
