Below is a list of the voice actors on The Simpsons, and the voices they provide. Voices provided by guest stars are in a separate list. Most of the cast do voices for several minor characters in each episode, but this page only lists regular characters.
Most of the artists voice more than one character. Homer Simpson's voice is provided by Dan Castellaneta. Julie Kavner provides the voice for Marge and the other female Bouviers; Nancy Cartwright does Bart; and Yeardley Smith solely does Lisa.
Maggie Roswell left the show during Season 10 due to a pay over her expenses. Marcia Mitzman Gaven filled in for Roswell in her absense; her main character, Maude Flanders, was killed off in Alone Again, Natura-Diddly. Roswell returned in Season 14, voicing her other characters when necessary.
Wallace is always credited as a guest star.
Gaven replaced Maggie Roswell as these and other minor characters for Seasons 10-14
