Collin Lee was Greg Heffley's backup friend and Rowley Jefferson's one-time best friend. He appears in Diary of a Wimpy Kid, its movie adaptation, and the online book, and well as playing minor roles in Dog Days and The Ugly Truth.


Role in Diary of a Wimpy Kid

After Greg and Rowley break up their friendship, Rowley starts hanging out with Collin every day after school, and the two become close to the point that they make "Best Friend" t-shirts featuring each other and wear them to school. After dinner one night, Greg sees him and Rowley walking up to Rowley's house for a sleepover and decides to go to Fregley's house to show that he has other friend options as well. While inside, Greg starts to regret his decision and intends to leave, though he doesn't because Rowley and Collin are still in Rowley's front yard.

Role in Dog Days

When Susan Heffley starts a reading club in Greg's neighborhood, Collin is one of the boys who is forced to attend, though he bails out after the first meeting.

When Greg invites Rowley to a video game tournament at the Game Hut, he tells Rowley to tell his parents that he's going to Collin's house

Role in The Ugly Truth

Collin appears briefly during the Lock-In when everyone is playing icebreakers.

Diary of a Wimpy Kid (film)

Collin is played by Alex Ferris in the movie.

He appears many times at school, including class and when seeing Greg and Rowley with hot cocoa.

He also appears when Rowley dumps Greg, and when he's playing patrol at Rowley's house.

Collin also attends The Wizard of Oz play and the Mother and Son Sweetheart Dance with Rowley.

Role in the Online book

Collin plays a much more prominent role, taking up many of Rowley's significant roles from the books, such as being taught how to play the drums by Rodrick or Greg taking a nap at his place.


  • In the online book, Collin bears a strong resemblance to Alex Aruda. In the book series, his appearance is changed so that he is short and stout with curly hair and no glasses.
  • In the online book, Collin's house gets toilet papered. In Diary of a Wimpy Kid, the victim is changed to Gramma.
  • In the online book, according to Greg, Collin's dad has every Spider-Man comic book since 1968.
