Trini Martin is Topanga's best friend during the first year of high school. She is a very annoying girl who does not behave lady-like at all, which leads to Cory greatly disliking her. She feels that Topanga is the only one who truly understands her. She can call her in the middle of the night, not say a thing, and Topanga will still know who called.
Unsurprisingly, Cory shares that not many people tell Trini about parties.
She was portrayed by the late Brittany Murphy, who was known for starring in the movie 8 Mile with rapper Eminem and Clueless with Alicia Silverstone.
