On Gilmore Girls, Rory’s Chilton classmate Brad’s last name is Langford.
Brad is formally identified as Bradley “Brad” Langford, a student at the elite fictional prep school Chilton. He is portrayed by Adam Wylie and appears as a nervous but memorable classmate of Rory Gilmore, Paris Geller, and Tristan Dugray.
Brad is especially associated with his fear of Paris, whose intimidating personality makes him visibly anxious. His story also mirrors Wylie’s real-life theatrical background: Brad leaves Chilton for a Broadway production of Into the Woods, then later returns to the school. That departure gives the character a short but distinctive arc across the early seasons.
Viewers sometimes remember him simply as “Brad” or confuse his surname with the actor’s surname, Wylie. The character’s full name is Bradley Langford, so Langford is the specific last name requested by the question. His Chilton connection, stage ambitions, and comic anxiety make him one of the show’s recognizable supporting students.
