Natasha Joyce (Last name only mentioned in the online version) is a minor character appearing in a flashback in The Last Straw. According to Greg, Natasha was one of the girls he "kind of liked" during his sixth grade, and as such, he wrote an entire letter before Valentine's Day devoting his love to her. Natasha, however, gave him a card she was originally going to give to her friend Chantelle who was out sick that day, merely replacing Chantelle’s name with Greg’s. This caused Greg to "lose interest" in her shortly thereafter. She may have also appeared in Cabin Fever as one of the girls that were arguing with Mr. Underwood about how the girls should do the boy's hard type of push ups in Phys Ed resembled her.
- Her look is different in Diary of a Wimpy Kid Online, where she appears to look like Piper Matthews.
