Family Guy has been making audiences laugh since 1999, and one big reason for its lasting popularity is its incredible lineup of celebrity guest stars. Over the years, hundreds of famous faces have lent their voices to the show, often playing hilarious or unexpected versions of themselves.
Some appearances were so funny or surprising that fans still talk about them today. Here are 16 guest stars who truly left their mark on Quahog.
1. Carrie Fisher
Few guest appearances on Family Guy hit as hard as Carrie Fisher’s recurring role as Peter’s boss Angela. She brought a sharp, deadpan energy to the character that made every scene feel electric.
Angela was tough, sarcastic, and oddly lovable all at once.
Fisher voiced the role across multiple seasons, making Angela one of the most memorable recurring figures on the show. Her passing in 2016 left a real void, and the writers honored her beautifully in a touching tribute episode that moved fans deeply.
2. Rush Limbaugh
Sometimes the most surprising casting choices turn out to be the funniest. Rush Limbaugh voiced himself in a 2009 episode, appearing in a segment that poked fun at political media in classic Family Guy style.
The fact that he agreed to appear on the notoriously edgy show surprised a lot of people.
His willingness to be in on the joke gave the episode an extra layer of comedy. It showed that even real-world public figures could laugh at themselves when the writing was sharp enough.
3. Adam West
Adam West was not just a guest star on Family Guy – he was practically a cast member. He voiced the hilariously eccentric Mayor Adam West for years, playing a fictional version of himself with total commitment and perfect comedic timing.
West clearly loved the role, leaning into every absurd joke with genuine enthusiasm. His chemistry with the regular cast was undeniable.
When he passed away in 2017, the show paid tribute with an emotional episode that celebrated everything fans loved about him.
4. Gene Simmons
Rock legends do not always make great TV guests, but Gene Simmons of KISS proved to be a natural. He voiced himself in a memorable episode where his over-the-top personality fit perfectly into the world of Quahog.
The show leaned hard into his reputation as a larger-than-life showman.
Simmons played along with jokes at his own expense, which made the whole thing feel genuinely fun rather than forced. His appearance reminded viewers that Family Guy works best when celebrities are willing to be totally ridiculous.
5. Miley Cyrus
Miley Cyrus brought something unexpected to Family Guy when she voiced Meg’s friend Missy in a season eight episode. Rather than playing a version of herself, she took on a fully fictional character, which showed off her voice acting range in a fun way.
Her performance was bubbly and confident, blending naturally with the show’s humor. Fans of Cyrus were excited to hear her in animated form, and the episode gave Meg more screen time than usual, which was a welcome change for fans of the underdog character.
6. James Woods
James Woods became one of Family Guy’s most beloved recurring gags. His fictional self was portrayed as vain, impulsive, and obsessed with shiny objects like candy – a running joke that fans absolutely adored.
The bit started in one episode and kept coming back because audiences could not get enough.
Woods voiced himself multiple times, always committing fully to the self-deprecating humor. The joke of luring him with a trail of candy became iconic.
It is a perfect example of how Family Guy turns a simple idea into comedy gold through repetition.
7. Liam Neeson
Liam Neeson brought his famous intense screen presence to Family Guy in a way that was perfectly self-aware. He voiced himself in an episode that played on his well-known Taken persona, using his deep, threatening voice for maximum comedic effect.
The contrast between his serious delivery and the silly Family Guy world was comedy gold.
Neeson has always shown a good sense of humor about his tough-guy image, and this appearance confirmed it. Fans who loved his action movies got an extra kick out of hearing him in cartoon form.
8. Patrick Stewart
Patrick Stewart’s appearance on Family Guy was a treat for sci-fi fans everywhere. He voiced himself with his signature dignified delivery, which the writers used as a perfect comedic contrast against Peter Griffin’s chaos.
Stewart has never been afraid to poke fun at his own serious reputation.
His scenes crackled with dry wit and perfect timing. Getting a classically trained Shakespearean actor to play along with Family Guy’s absurd humor was a bold creative move, and it paid off brilliantly.
Stewart seemed to genuinely enjoy every moment of it.
9. Bryan Cranston
Before he was Walter White, Bryan Cranston was already well known to TV audiences, so his Family Guy appearance carried plenty of star power. He voiced himself with the kind of committed, slightly manic energy that fans recognized from his other work.
The writers clearly had fun with his reputation for intense performances.
Cranston leaned into the jokes about his career with ease. His natural comedic instincts, sharpened during his Malcolm in the Middle years, made the performance feel loose and genuinely funny rather than like a stiff celebrity cameo.
10. Drew Barrymore
Drew Barrymore voiced a love interest for Quagmire in a surprisingly sweet episode that gave the show’s most notorious womanizer an unexpected emotional moment. Her warm, breezy vocal style brought genuine charm to the character, making audiences actually root for the romance.
Barrymore has always had an effortless likability, and that quality translated perfectly into voice work. The episode balanced Family Guy’s usual edgy humor with something a little more heartfelt, and Barrymore’s performance was a big reason why it worked as well as it did.
11. Alec Baldwin
Alec Baldwin has a gift for playing pompous, self-important characters, so casting him on Family Guy felt almost too perfect. He voiced himself in an episode that leaned heavily into his reputation for being outspoken and larger than life.
Every line he delivered had that unmistakable Baldwin swagger.
The writers gave him material that matched his comedic strengths from 30 Rock and SNL, and Baldwin ran with it. His appearance felt less like a celebrity cameo and more like a natural extension of characters he had been playing his whole career.
12. Jennifer Love Hewitt
Jennifer Love Hewitt voiced a character named Caitlin in a season three episode, and her performance brought a playful, self-aware quality to the role. The show found clever ways to reference her real-life public image, which added an extra layer of humor for fans who recognized the winks.
Hewitt played along with the jokes gracefully, showing she had a sense of humor about her own celebrity persona. Her willingness to lean into the comedy made the episode memorable and helped cement her status as one of the show’s more charming one-time guests.
13. Donny Most
Happy Days fans got a fun surprise when Donny Most, famous for playing Ralph Malph, showed up on Family Guy. His appearance was packed with nostalgic references that older viewers absolutely loved, while younger fans got a quick and funny crash course in 1970s TV history.
Most played himself with a cheerful willingness to be the butt of a few jokes, which is always endearing. Family Guy has a long tradition of celebrating and gently roasting pop culture icons, and Most fit right into that tradition with ease and good humor.
14. Meg Ryan
Romantic comedy royalty Meg Ryan brought her signature warmth to a Family Guy episode that put a hilarious spin on her real-world image. The show is known for subverting expectations, and casting someone as universally beloved as Ryan allowed the writers to play with that likability in clever ways.
Her voice performance was charming and funny in equal measure. Ryan seemed comfortable with the show’s irreverent tone, which made the whole thing feel like a genuine collaboration rather than a celebrity just collecting an easy paycheck for a quick cameo appearance.
15. Carol Burnett
Having Carol Burnett on Family Guy was a genuine landmark moment. One of the greatest comedians in television history, Burnett brought class, warmth, and impeccable timing to her guest role.
Her presence elevated the episode in a way that few other guest stars could have managed.
Burnett voiced herself, and the writers clearly had deep respect for her legacy, crafting material that celebrated rather than mocked her. For longtime fans of classic TV comedy, seeing her name in the credits was pure excitement.
She delivered every line with effortless, seasoned brilliance.
16. Ryan Reynolds
Ryan Reynolds is one of the funniest people working in Hollywood today, so his Family Guy appearance felt like a match made in animated heaven. His quick wit and natural comedic rhythm translated beautifully into voice acting, and he clearly had a blast recording his lines.
Reynolds voiced himself with the same self-deprecating humor he brings to his social media presence and Deadpool films. The episode gave him room to riff, and he made the most of every moment.
Fans agreed it was one of the funnier celebrity cameos the show had done in years.
