Bart Simpson is voiced primarily by American voice actor Nancy Cartwright, who has played the role since the character debuted on The Simpsons in 1989. Cast early in development alongside Homer, Marge, and Lisa, Bart became one of the show’s defining voices and a signature element of its comedic style. This guide outlines the main cast for Bart, compares alternate recordings, and clarifies the actor’s ongoing role in the series.
Primary Voice Actor for Bart Simpson
Nancy Cartwright has voiced Bart Simpson for nearly all of the character’s screen life. She originally auditioned for the role of Lisa but was directed to read for Bart, where her energetic delivery matched the show’s vision. Cartwright’s vocal performance anchors the series and is central to Bart’s mischievous yet expressive tone.
Alternate Voices and Early Auditions
Before Nancy Cartwright was cast, other child actors tested lines for Bart during development. Yeardley Smith read for the role early on, while several other young performers recorded demo tapes. Production chose Cartwright after tests highlighted her ability to balance mischief, vulnerability, and timing.
Notable Alternate Recordings
Although rare, alternate recordings exist for archival, promotional, or dialect purposes. These versions typically align closely with Cartwright’s original takes and are used sparingly. For most audiences, the canonical voice of Bart remains consistent and unmistakable.

Occasionally, other performers have voiced Bart for language dubs, promotional segments, or novelty recordings, but the core English-language version remains Nancy Cartwright. In localized adaptations, regional voice actors may perform the role, but this does not change the primary cast attribution for the original series.

Consistency in casting has helped preserve the character’s tone, with Cartwright’s interpretation remaining central. Producers have affirmed no plans to recast the role, underlining continuity as an essential element of the show’s enduring appeal.
