What is the name of Will's snobbish cousin on the show?

Will's snobbish cousin on The Fresh Prince of Bel-Air is Carlton Banks. Carlton is Philip and Vivian Banks's son, a privileged and academically focused teenager whose polished manners and conservative outlook often clash with Will's streetwise personality.

Alfonso Ribeiro played Carlton throughout the original sitcom. The character is famous for his intense school ambition, preppy style, and enthusiastic dancing, especially the routine later known as “The Carlton,” which became one of the show's most recognizable comedic moments.

Carlton is sometimes mixed up with Will's other cousins. Ashley Banks is the younger sister who struggles with expectations placed on her, Hilary Banks is the older daughter known for her vanity and fashion interests, and Jazz is Will's friend rather than a Banks cousin. Carlton's full name is Carlton Banks, but “Carlton” is the standard canonical answer to this question.

Although Carlton begins as Will's spoiled and judgmental foil, their relationship develops into a genuine brotherly bond. Several episodes explore Carlton's pressure to succeed, his vulnerability, and the ways Will's influence broadens his perspective.
