|'ll be famous one day, but for now I'm stuck in middle school with a bunch of morons.||”|
Gregory "Greg" Heffley is an American middle school student, and the main protagonist of the Diary of a Wimpy Kid series. He is believed to be loosely based on Jeff Kinney when he was in middle school. Greg is very concerned about his popularity level and how he looks in public. He absolutely loves video games and slacking off, taking after his older brother Rodrick Heffley. He takes up a lot of traits from Rodrick (such as selfishness, being a slacker, etc.). He also has an interest in cartooning and making comics. He was played by Zachary Gordon in the live-action movies Diary of a Wimpy Kid, Diary of a Wimpy Kid: Rodrick Rules, and Diary of a Wimpy Kid: Dog Days, even though the books are whiteboard animated. Greg is portrayed by Jason Drucker in the live-action film, Diary of a Wimpy Kid: The Long Haul.
Greg is lazy, petty, slightly narcissistic, egotistical, usually backstabbing, and sometimes even selfish and dishonest, and apparently lacks talent. He hardly has any skills aside from video games and possibly singing. However, despite all this, Greg still has had his kind and caring moments, it's just that, it's not that often. He hates taking blame for anything, and would much rather not take all the credit.
Greg explains and narrates throughout the series that he has no strong talents, other than video games and comics. As such, he spends most of his time on them, which deters him away from schoolwork and chores. For a time, he harboured a hope of drawing for the school newspaper, but his comic was bowdlerized by the editor (Mr. Ira) and Rowley’s comic, which was also Greg's idea, was better liked by the people at his school. He hardly shows any other talents. However, Greg is probably good at singing, due to the fact that when he was auditioning for the school play, the drama teacher told him he had a nice soprano (high male) voice, and is also good at sewing, but he complains that these talents do not make him stand out.
Greg almost always tries to find a scapegoat to put the blame on for his behaviour, but he is oblivious to the fact that nobody forced or influenced him, other than probably his older brother, Rodrick, to act in this manner. Very few times has Greg actually admitted to being "wrong" in a decision he made and took responsibility for it. It should also be noted that while Greg is arguably a watered down version of Rodrick, he does not have any productive interests and could actually be considered more hurtful than Rodrick psychologically.
Although he's considered a "Wimp", he has a problematic behaviour in many cases, and he often puts himself and his family into trouble. Typically he is looking to find a scapegoat to blame, and only in very rare occasions does he admits being "wrong", but he also seems to care for others and, as such, is willing to give himself to people he loves, especially Rodrick. The parents of his best friend, Rowley, believe Greg is a bad influence on their son (mainly Rowley's dad) because he sometimes gets bad grades in school, does not focus on his studies like he's supposed to, and barely listens to his parents.
Greg wants to be famous when he grows up, and imagines it many times.
He is very petty in order to win.
Greg always has an exaggerated thought, being confident of being rich and famous. He also kind of bullies and use Rowley much more than needed, as he often thinks of hurting him and makes him do a lot of his work, like giving him piggy-rides, looking out for dog-poop, and completing Greg's English work since Greg is not good at writing in cursive, though Greg believes that he is doing it for a good cause. Although Greg is shown not to be hostile towards Rowley, in Rowley's diary, Diary of an Awesome, Friendly Kid, Greg can be seen shouting at Rowley for trying out his retainer.
He also had an extremely huge crush on Holly Hills, when she turned up at the seventh graders' roller rink.(Rodrick Rules film) Holly Hills was a new seventh grader at Westmore middle school whom he fell deeply in love with. In the film Rodrick Rules and Dog Days, he put in so much effort to win Holly all to himself, which was what Rodrick was reading out loud from Greg's diary in The film Rodrick Rules. After Heather Hill's Sweet Sixteen party in the film Dog Days, she took Greg's hand, indicating she liked him back and she thinks Greg is really amusing.
However, in the books, Greg lost interest in Holly after she mistook him for Fregley.
Greg is usually depicted with black shorts, or black pants (sometimes black jeans, or, when he is fantasizing, a black tuxedo) and a white shirt. He is very skinny and does not seem to eat nor work out much. His father has tried to get him to work out and exercise, but he prefers playing video games. His nose is a simple oval but stops where the first eye is while his ears are circled. His head is a circle but stops where around the eyes. He also appears to wear contact lenses, which he mentioned in The Third Wheel and The Last Straw, and wears his backup glasses when he runs out. Greg also has a retainer as mentioned in Diary of an Awesome, Friendly Kid and a headgear as shown in The Ugly Truth. He also wears white shoes or white sandals (as shown in "Dog Days")
In the movie, he has brown hair and pale white skin. Like in the book, he's visually skinny and shorter than Rowley.

- It is possible that Greg has hyperthymesia- a condition that lets the individual to recall almost everything in their life. However, in previous books, he is shown to have a bad memory. It is most likely that he is inventing memories and has simply been told by his parents about life before birth. He talks about his time in pre-school, but this is not unusual as most people's first memories occur age 1-2.
- Greg has went under detention three times:
- Greg was only 5 pounds 7 ounces at birth with average being 7.5 pounds, though newborns may vary from 5.5-10 pounds, this may be as he was born 3 weeks premature, even though most children born up to 1 month premature are of normal weight.
- He is the only member of his family who did not serve as a main antagonist in any book. The other members of his family serves as a main antagonist in at least one book (Rodrick in Rodrick Rules, Frank in The Last Straw, Susan in Dog Days, and Manny in Cabin Fever).

- It is revealed in The Last Straw that Greg swears a lot, often swearing at school and even swearing in front of his toddler brother, Manny and also using "made-up" swears like "Raspberry Plastic Tickle Bear!", etc.

- Greg is rarely seen smiling.
- Also, none of the Wimpy Kid books' covers feature Greg smiling. However, The original Do-It-Yourself Book's cover has Greg smiling.
- Greg once fainted after seeing crickets in a box. Usually it is a childish habit of fainting at the sight of insects and arachnids, considering Greg is nearly a teenager.
