List of SpongeBob SquarePants cast members

SpongeBob SquarePants is an American animated television series created by marine biologist and animator Stephen Hillenburg that debuted on Nickelodeon in the United States on May 1, 1999. The show employs six main voice actors, and numerous regular cast and recurring guest stars. The principal voice cast consists of Tom Kenny, Bill Fagerbakke, Rodger Bumpass, Clancy Brown, Mr. Lawrence and Carolyn Lawrence. Supporting cast include Jill Talley, Mary Jo Catlett, Lori Alan, Dee Bradley Baker, Brian Doyle-Murray, Sirena Irwin, Bob Joles, Mark Fite and Thomas F. Wilson, while Ernest Borgnine, Tim Conway and Marion Ross have appeared as repeat guest cast members.

SpongeBob SquarePants chronicles the adventures and endeavors of the title character and his various friends in the fictional underwater city of Bikini Bottom. Many of the ideas for the show originated in an unpublished, educational comic book titled The Intertidal Zone, which Hillenburg created in the mid-1980s. He began developing SpongeBob SquarePants into a television series in 1996 upon the cancellation of Rocko's Modern Life, another Nickelodeon animated series which Hillenburg directed. While creating the show, Hillenburg, with colleague Derek Drymon, was also conducting auditions to find voices for the show's characters. He turned to Kenny, who had worked with him on Rocko's Modern Life, to voice the title character. The voice of SpongeBob was originally used by Kenny for a very minor female alligator character named Al on that series.
