Peter Griffin (Born Justin Peter Griffin) is the protagonist of the show and title character. He's a man of Irish descent currently residing in Quahog, Rhode Island with his wife Lois Griffin. In "Padre de Familia", he was born in Mexico, where his father had taken mother unsuccessfully to the exterme bull fighting and make her give to peter In A Portable toilet Peter agreed to abandon a revolt of his father-in-law Carter Pewterschmidt's servants in exchange for him using his connections to make Peter a United States citizen. According to "I Dream of Jesus", Peter attended Providence High School. Together, Peter and Lois have three children, Chris, Meg, and baby Stewie. After a mix up at a sperm bank, Peter also became the biological father of Bertram. In addition, he and Lois had a child named Peter Griffin Jr. who died when Peter shook him too much as revealed in "The Juice Is Loose". Out of pity he also adopted an intellectual talking dog named Brian who formerly lived on the street as a stray, an accepted fact in Brian's two adoption stories. In The Real Live Griffins he was portrayed by Danny DeVito.

Peter's age comes into question in "Baby, You Knock Me Out". Peter should turn 45 but no age is identified in the episode. In "The Tan Aquatic with Steve Zissou", Lois says that he's 42. Lois does say that she is 42 at this time, which would match the age difference stated in "Let's Go to the Hop" and ignore their both being 19 in "Meet the Quagmires". Lois herself would later turn 44 in "Lois Comes Out of Her Shell".


Peter's favorite pastime is watching TV, with his favorite shows consisting of Star Trek, Three's Company and Charles in Charge. He is also a huge KISS fan and followed them during the KISS Stock shows and even got a copy of Kiss Saves Santa for Christmas. Peter is also an ardent fan of Barry Manilow, though this is a fact he has been known to deny in public. Peter also mentioned that he enjoys the following breakfast cereals: Total, Trix, and Boo Berry.

An I.Q. test in "Petarded" confirms that his low intellect places him in a category below mentally retarded. He rushes off to attend Quahog College just to count to three in "3 Acts of God". His mental shortcomings have resulted in various accidents to other people; most notably the death of his step-father Francis Griffin, and injuries on multiple occasions to his wife Lois. His attention span is also incredibly short. When he discovers his mental retardation in the episode, he closes his eyes while driving, wishing "it would all be over" and hitting Tom Tucker with his car instead. Given his short attention span, as well as his erratic and frequently inappropriate behavior, it is conceivable that Peter suffers from Attention Deficit Hyperactivity Disorder, or ADHD. In addition, Peter is often seen getting hurt mostly by his own fault. When trying to impress Chris with his forward-thinking, Peter claims it is still 1988 in "Baby Got Black".

Peter also has a habit of proving his masculinity, not wanting Lois to fall for another man. He is incredibly jealous of other attractions Lois has in her life, an attitude that tends to get out of hand in most cases; in "Stuck Together, Torn Apart", he goes so far as to punch his reflection in the mirror after Lois comments on it being handsome. In "Brian Sings and Swings", he tells Lois, "Remember what I always tell you, if I come home in the middle of the day and catch you having sex with someone, I'll kill you both" though when he catches her in bed with Bill Clinton in "Bill and Peter's Bogus Journey", he takes no hostile actions whatsoever. However, he seems not to mind the fact that she slept with other men before they met, just so long as she doesn't do so again; he is particularly proud of the fact that she once slept with Gene Simmons of Kiss when he discovers this in "Road to Europe", but forbids any sexual activity between the two now as seen in "Don't Make Me Over".

Peter seems to find it frustrating that he is "wrong" while Lois is "right" about issues all the time, and apparently takes these issues competitively, just waiting for the day she slips up. This day finally comes in "PTV" after settling a conflict with Lois about censorship on television that she appeared sure to win. In an ironic twist that forces Lois to concede defeat, Peter celebrates by opening a secret compartment within the ceiling containing balloons, streamers, confetti, and a banner reading "PETER'S RIGHT!"; Peter then claims that he set this up 15 years ago, suggesting that this had been a pretty major issue for him for quite some time. Curiously, in "Da Boom", after Lois admits he was right about the end of the world and she was wrong, Peter makes no reference to the compartment, though he had been bragging about his "victory" for two weeks straight.

Among the members of his family, he tends to treat Meg with the least respect; in "Peter's Daughter", for example, he reminisces about the various pranks he played on her, including tripping her, flicking her nose with his finger, and even shooting her at one point. Also, he wipes a boogie on her hat saying "Hey Meg...proud of you". He is known to embarrass her at times and with things that mean the most to Meg; the entire family once huddled together to read her diary and continue after Meg catches them. However, some episodes of the series show Peter developing greater respect and unity between himself and his daughter such as in "Road to Rupert", the aforementioned "Peter's Daughter" and "Meg Stinks!", though these moments tend not to last for very long.

"I Dream of Jesus" reveals that his favorite song is the Trashmen's "Surfin' Bird", and loves the song to the point of repeatedly singing it, playing the record of it, and trying to convince others that "the bird is the word". In "Wasted Talent", a running gag debuted when someone, usually Peter, will be running and fall and then hold his shin exclaiming the sound "Ssss Ahhhh" once or multiple times.


Aside from Brian, Peter's best friends are Glenn Quagmire, Joe Swanson, Cleveland Brown and Jimmy Wendell Colton VII. They enjoy hanging out at their local bar, The Drunken Clam, drinking and chewing the fat. The four men do many things together. Once the four friends entered and won a costume contest at an 80s TV convention, dressing up as the A-Team. On another occasion, their fishing boat was wrecked, and they were stranded together on a desert island. Peter also has other friends such as Mort and Muriel Goldman and nudists Dave and Dotty Campbell, with whom he is seen occasionally. He became friends with Brian's ex-girlfriend Jillian, which stems from their below average intelligence; she even asked him to give a speech at her wedding.

Employment HistoryEdit

Peter first met Lois while he was working as a towel boy for Marguerite Pewterschmidt. He worked at the Happy-Go-Lucky Toy Factory for the bizarre Mr. Weed for the first three seasons of the show. But when Mr. Weed was accidentally killed by choking on a dinner roll on which Brian had originally been choking, Peter was out of a job and had to find work elsewhere.

To date, Peter has been employed as a toymaker, knight and a fisherman. In "The Perfect Castaway" during a desperate attempt to catch more fish at a private island, Peter's boat is destroyed by a hurricane. Despite surviving the hurricane, with the loss of his boat, Peter is again jobless. In "Jungle Love", Peter goes to the unemployment office, and obtains a job at the Pawtucket Brewery. Initially he is placed on the line, but after over-indulging in the free ale, he is demoted to the shipping department, working with Opie and under Angela.

Ernie The Giant ChickenEdit

In a running gag, storylines are interrupted by unexpected fights between Peter and a giant chicken. These battles feature long strings of action film-style sequences, with explosions, high-speed chases, and excessive collateral damage to both property and innocent bystanders, ending with Peter the victor leaving the giant chicken for dead, only for a sudden movement to show that the chicken is still alive.

In "Da Boom", the feud starts over a trivial incident where the chicken gives Peter an expired coupon at the grocery store. The fight resumes in "Blind Ambition". In "No Chris Left Behind" the chicken is identified as "Ernie", and he has a wife named Nicole, also a giant chicken. Peter is invited to dinner with them after they realize that their fighting is pointless, but then they argue over who will pay the bill, and the fighting starts all over again. Ernie makes a brief, non-fighting appearance in "Meet the Quagmires", in which Peter unwittingly assaults the giant chicken at a 90s dance, retroactively providing Ernie with a grudge against Peter. Ernie the chicken appears in the Star Wars parody episodes Something, Something, Something, Dark Side and It's A Trap!, as the infamous bounty hunter Boba Fett.

Ernie was also mentioned in "New Kidney in Town". When Peter was hospitalized due to kidney failure, Brian offered to give Peter his kidney. In response to the family's shock, Dr. Hartman stated that this transplant was not the only crazy thing that took place in medical research, and said that he once attempted to clone a chicken. This resulted in the original chicken to grow human-sized, violent, and incredibly hostile. Peter paused at this, and stated "now watch me whip now watch me nae nae."

One day... Ernie will defeat Peter and claim domance.


Despite being obese, a heavy drinker, and accident-prone, Peter appears to be in great health. Periodically, in typical cartoon fashion, Peter is shown recovering quickly from serious injuries, such as losing all the fingers on his right hand while handling M-70 firecrackers. In spite of the injury, he has no visible scarring on his hand. In some episodes he displays enormous strength, such as when single handedly challenging a professional football team in "Patriot Games". According to "The Father, the Son, and the Holy Fonz", Peter played high school football and his sister mentions his wearing a bra while playing in "Peter's Sister".

Peter asserts that he weighs 299lbs in "Vestigial Peter", the same as he did in grade school. In "Spies Reminiscent of Us", during Peter's "poop montage", he loses over 50 pounds; going from around 330 lbs to 260 lbs.

He underwent a vasectomy in "Sibling Rivalry".

Occasionally Peter soils himself, prominently featured in "Death Lives" and "When You Wish Upon a Weinstein". After these accidents, he never seems to notice that it was a result of his own behavior.

Episodes like "Mr. Saturday Knight", "Model Misbehavior", "Deep Throats", "Peter's Two Dads" and "April in Quahog" show that Peter has used various drugs such as LSD, Meth, "ecstasy", marijuana, steroids, cocaine, and crack cocaine, but has managed to avoid incarceration and long-term effects from the use of these drugs.

In "McStroke", after eating thirty hamburgers in one sitting, Peter suffered a stroke that paralyzed the left side of his body. For the next three months he walked with a limp, his arm and leg hung lifelessly from his body, and his eye and part of his mouth had slid down his face, giving him a speech impediment. This damage was reversed completely after a five minute session at a stem cell research facility.

In "The Fat Guy Strangler", Peter's mass causes him to have his own gravitational pull, shown when Brian threw an apple, a glass of water, a book and a Television, which immediately started to orbit his body.

In "I Take Thee Quagmire", it is revealed that Peter used to smoke. Peter also smokes during a modern-day cutaway gag break in "Back to the Pilot".

In "Not All Dogs Go To Heaven", Peter reveals as a child he was never immunized for the mumps.

In "New Kidney in Town", Peter suffers a kidney failure from a homemade energy drink. Brian offers do donate his kidneys, which would kill him. Before the surgery, Dr. Hartman offers to give up one of his kidneys, which he does and reveals that Brian's kidneys could not have been transferred to Peter's body.

Peter's estranged sister Karen Griffin visits for Thanksgiving in "Peter's Sister" and reveals several personal details to his friends, including that when upset, he stutters and pees his pants.


Peter Griffin has undeniably proven to be a complete idiot. Every episode features him making stupid, unintelligent comments followed by him performing a ridiculous action. He never learns from his mistakes and will always go right back to doing them again. All in all, he's your everyday comedic idiot and definitely falls under the "stupid" category.

Looking deeper into Peter's stupidity, we can see that most of his brainless behavior seems to be done out of immaturity. At times he demonstrates the intelligence level of a teenage boy in his "jackass" phase, pulling off dumb and dangerous stunts that only get him hurt and at other times, he acts like a four year old boy, taking on the personality of a little kid perfectly.

In the episode Petarded, it was revealed that Peter Griffin was mentally retarded, falling just under the retarded category, after winning a game of Trivial Pursuit which Lois rigged with questions from the Pre-school edition so he could win, he thinks that he is a genius, and at Brian's prompting he takes an exam to apply for the MacArthur Genius Grant, which he fails so awfully that he is found to be mentally retarded, falling just under the line of retarded people.

In the episode Tales of a Third Grade Nothing, it was revealed that Peter never passed the third grade. He passed by the end of the episode, but this still means that he has a third grade level of intelligence. Despite having not passed the third grade in this episode, he was seen passing the fourth grade in the episode And Their Weiner Is .... He was a full grown adult when he did, so I guess you can make up the theory that the events of this episode happened after the events of Tales of a Third Grade Nothing. Also, there's been a lot of flashbacks to him in middle school and high school and college in the show, so I guess it's reasonable to say that even though he never technically passed those grades, the school board still let him move on to other grades and he can just go back to those classes and waste his time on school whenever he wants.

Peter has shown some sparks of being smarter than those around him, such as in "Back to the Woods" when James Woods returns to get revenge, Peter and Brian get rid of him exactly the same way they did the first time, using a box and trail of candy, he makes a point that next time Woods shows up they should do that in the beginning as he has already fallen for it twice.

Peter does have ideas he thinks are smart but often back fire, such as in "FOX-y Lady" when he got his new drivers license he decided to have the picture taken when he was drunk, so if a cop pulled him over for DUI when he looked at his license he would think he was just fine.

Also despite being married to Lois for 20 years, he was unable to realize she was in danger in "And Then There Were Fewer" despite her acting very odd. As well as was more interested in listening to his songs than to pay any real attention. He also firmly believed that Derek Wilcox was a God due to the fact the picture on his phone made him look as if he was holding up the Hollywood sign, despite Derek clearing explaining to him it was merely a camera trick.


Peter's car strongly resembles a 1977 Ford LTD Station Wagon although no specific brand has been mentioned and in the commentary for "Road to Rupert" there is a remark about it having a flip-down TV in a mid-'81s station wagon.


Peter has a crapton of relatives. Read the category "Griffin Family" to learn more about them. Also read "Pewterschmidt Family" to learn about his indirect family members of Lois' side of the family.
