The Simpsons is an animated sitcom built around a large ensemble of characters who live in the fictional town of Springfield. While the show centers on the Simpson family, its world includes dozens of recurring residents, institutions, and one-off figures used to satirize American life. Characters range from central protagonists to minor extras; many have become cultural icons with distinctive traits, catchphrases and running gags.

Principal characters

  • Homer Simpson — The bumbling, often selfish father who works at the Springfield Nuclear Power Plant; known for impulsiveness and a few signature exclamations.
  • Marge Simpson — The patient, moral center of the family; recognizable by her tall blue hair and steady caretaking role.
  • Bart Simpson — The mischievous son and prankster; a symbol of youthful rebellion in many early episodes.
  • Lisa Simpson — The intelligent, idealistic daughter with interests in music, politics and environmental issues.
  • Maggie Simpson — The infant of the family, often silent but occasionally starring in visual gags and key episodes.

Recurring characters and households

  • The Flanders family — Ned Flanders is Homer’s devout neighbor; his children and late-wife figure in many moral-contrast stories.
  • Mr. Burns and Waylon Smithers — The wealthy, tyrannical owner of the power plant and his loyal assistant.
  • Krusty the Clown — A jaded television entertainer whose show lampoons the entertainment industry.
  • Moe Szyslak, Chief Wiggum, Principal Skinner — Local authority figures and business owners who populate Springfield’s everyday life.
  • Sideshow Bob, Milhouse, Barney, Patty & Selma — Frequent foils, friends and extended relatives who recur across storylines.

The series deliberately mixes grounded family stories with exaggerated or surreal characters; some citizens appear briefly while others develop long-running arcs and memorable personal histories.

Creation, voices and development

Matt Groening created the Simpsons characters for short segments before the series expanded into a half-hour program. A small core group of voice actors perform many roles: among the best-known are Dan Castellaneta, Julie Kavner, Nancy Cartwright and Yeardley Smith, along with a group who voiced multiple supporting parts. Over time, the show’s producers and cast have adjusted roles in response to social conversation about representation.

Impact, uses and notable facts
