Mariana Mendoza is a character who is known for holding legendary middle school Halloween parties. The parties are legendary because her parents Mr. Mendoza and Mrs. Mendoza let her hold whatever kind of party she wants (even allowing her to play super loud music) as long as it stays in the basement.

One year so many people were invited that the party spilled outside and the police had to come shut it down. As a result, the next year she says she will only invite the middle school band, and ultimately invites only the woodwind section of the band. Because wanting to go to her party and had Rowley Jefferson in the woodwind section, Greg Heffley told him to be a "two-headed monster", so he can come with him too. But Susan Heffley, came with them, ended up making the party not a madness, which made Greg a target for the boys at the party for ruining their "fun".


  • Greg said that she sat next to Rowley Jefferson in Music Class.
  • It's possible that Mariana is related to Emilio Mendoza, as they share the same last name.
  • It's likely that Mariana Mendoza is of Hispanic descent, given her name.
