Simpsons Characters: Complete Family Facts and List

Think of the most iconic television family, and chances are the Simpsons come to mind. Since December 17, 1989, viewers have watched Homer, Marge, Bart, Lisa, and Maggie stumble through life in Springfield — and along the way, the show has introduced over 900 named characters.

Total named characters: 900+ · Main family members: 5 · First episode aired: December 17, 1989 · Seasons as of 2025: 36

The pattern: the Simpson household is kept deliberately small, giving each member space to develop distinct personality traits that have sustained 36 seasons of storytelling.

The implication: the Simpson family’s small size is a deliberate creative choice — it forces the writers to develop each character deeply rather than spreading attention across a large clan.

Who Are the Five Simpsons?

• Homer Simpson — the bumbling but loving father, voiced by Dan Castellaneta (Simpsons Wiki cast listing)
• Marge Simpson — the patient matriarch with the iconic blue beehive, voiced by Julie Kavner (Simpsons Wiki cast listing)
• Bart Simpson — the mischievous 10-year-old, voiced by Nancy Cartwright (Simpsons Wiki cast listing)
• Lisa Simpson — the intellectual 8-year-old saxophonist, voiced by Yeardley Smith (Simpsons Wiki cast listing)
• Maggie Simpson — the perpetually pacifier-sucking baby, known for her first word

The five Simpsons are the show’s fixed gravitational center. Around them orbits a massive supporting cast of co-workers, teachers, family friends, extended relatives, townspeople, and local celebrities — all catalogued in comprehensive reference lists (Wikipedia character list). The pattern: the tight family unit creates a stable core that lets the sprawling cast feel expansive without losing focus.

When did Marge get pregnant?

Marge became pregnant with Bart in the season 3 episode “I Married Marge,” which aired in 1991. The episode reveals that Marge was already pregnant when she and Homer got married in a small chapel — a moment that set the tone for their chaotic family life (Wikipedia character list).

What Is Maggie’s First Word?

Maggie Simpson’s canonical first word is “Daddy,” revealed in the season 6 episode “Maggie Makes Three.” After Homer quits his job at the nuclear plant to work at the bowling alley, Maggie — left at the daycare — utters “Daddy” just as the family realizes they need Homer’s old job back (Wikipedia character list).

In a later episode, “Lisa’s First Word” (season 4), Maggie says “Homer” in her sleep, but writers have confirmed “Daddy” remains the official first word. This small detail has become one of the most searched Simpsons trivia points. The implication: even minor canon moments generate lasting fan interest.

Who Is Bart’s Biological Father?

Homer Simpson is canonically Bart’s biological father. The show has never seriously challenged this fact, despite several throwaway gags and non-canon Treehouse of Horror segments. In the episode “I Married Marge,” the timeline is made explicit: Marge was already pregnant with Bart when she married Homer, and Homer is the father (Wikipedia character list).

Does Bart have autism?

Bart Simpson has never been officially diagnosed with autism or ADHD by the show’s writers. Fan theories have circulated for years, often pointing to his impulsivity, hyperactivity, and occasional difficulty with social cues. But according to Wikipedia’s character listing, no canonical episode confirms any neurodevelopmental diagnosis. The show’s creators have not commented on these theories.

Who has ADHD in The Simpsons?

No Simpsons character has been officially labeled with ADHD. Fans have speculated that Bart’s attention-seeking behavior and Ralph Wiggum’s quirky nature might align with certain traits, but these remain fan interpretations, not confirmed storylines.

Who is Bart’s twin brother?

Bart’s twin brother appears only in a non-canon segment from the Treehouse of Horror XXI episode, a Halloween special that exists outside the show’s main continuity. The character, named “Twin Bart,” is a one-off gag and not considered part of the official Simpsons universe (Wikipedia character list).

What Are Some of the Most Popular Simpson Characters?

Beyond the core five, a constellation of Springfield residents has achieved iconic status. According to fan rankings and reference pages (List Challenges fan rankings), these characters consistently top popularity charts:

• Mr. Burns — the elderly, miserly owner of the Springfield Nuclear Power Plant
• Moe Szyslak — the depressed bartender of Moe’s Tavern
• Barney Gumble — Homer’s best friend and perennial barfly
• Lisa Simpson — the intellectual heart of the family, often ranked the most relatable character
• Ned Flanders — the overly cheerful, deeply religious neighbor

Who is the funniest Simpson character?

While humor is subjective, fan communities frequently cite Homer Simpson’s absurd one-liners and Moe Szyslak’s deadpan misery as the show’s finest comedic contributions. Reddit threads and list challenges (List Challenges fan rankings) often place Homer first, followed closely by Mr. Burns.

Who is the bus driver in The Simpsons?

The school bus driver is Otto Mann, a laid-back, long-haired hippie who drives Springfield Elementary’s bus. Otto is a recurring character known for his love of rock music and his general incompetence as a driver (Wikipedia character list).

Who is the bartender in The Simpsons?

Moe Szyslak is the bartender and owner of Moe’s Tavern, the town’s central watering hole. Voiced by Hank Azaria (until 2020) and now by additional voice actors, Moe is known for his prank calls, his unrequited crush on Marge, and his perpetually gloomy demeanor (Wikipedia character list).

Who is Radioactive Man in The Simpsons?

Radioactive Man is a fictional superhero within The Simpsons universe — a parody of classic comic-book heroes like Superman and Spider-Man. The character appears in comic books read by Bart and in the meta-episode “Radioactive Man” (season 7), where a film adaptation is attempted. Radioactive Man’s alter ego is Claude Kane III (Wikipedia character list).

What Is the Complete List of Simpsons Characters from A to Z?

Wikipedia maintains an exhaustive alphabetical list of Simpsons characters that runs hundreds of entries deep — from “Abe Simpson” to “Zutroy” (Wikipedia character list). The list covers main characters, supporting cast, one-time guest stars, and even characters who appear only in background scenes.

The sheer scale is staggering. Fan-compiled alphabetical lists on GitHub (GitHub Gist fan compilation) show how the show’s writers have created hundreds of distinct names for minor characters — from “Bumblebee Man” to “Professor Frink.” The Simpsons Wiki’s character category (Simpsons Wiki character category) also maintains a comprehensive index that includes current and former characters alike.

The implication: if you want the complete A-to-Z list, Wikipedia and the Simpsons Wiki are your best sources. The list is too long for any single article to reproduce — these are living documents updated with every new episode.

What Characters Are No Longer in The Simpsons?

Some of Springfield’s most memorable residents have left the show, either through on-screen death or behind-the-scenes changes:

• Maude Flanders — Ned Flanders’ wife died on-screen in season 11’s “Alone Again, Natura-Diddily.” She was killed by a T-shirt cannon at a stock-car race, a shocking moment that removed one of the show’s kindest characters.
• Edna Krabappel — Bart’s teacher was written out of the show after the death of voice actress Marcia Wallace in 2013. The character was retired with dignity — an off-screen retirement announced by Principal Skinner.
• Apu Nahasapeemapetilon — The Kwik-E-Mart owner’s status is uncertain after voice actor Hank Azaria stepped down from the role in 2020 following criticism about racial stereotyping. Apu has not appeared in new episodes since then, but the show has not officially killed off or retired the character (Wikipedia character list).

Other characters have faded from regular appearance without explanation — characters like “The Yes Guy” (from season 9) or “Lionel Hutz” (after Phil Hartman’s death) simply stopped appearing.

“I wanted a dysfunctional family that was still lovable.”

— Matt Groening, creator of The Simpsons (Wikipedia character list)

The pattern: characters leave The Simpsons through one of three doors — on-screen death, voice actor circumstances, or cultural sensitivity shifts. For the show’s future, the third category (Apu) may be the most consequential.

While this article focuses on the Simpson family, a detailed Simpsons characters full list covers the entire Springfield roster.
