What is the name of the neighborhood where Uncle Phil lives?

The neighborhood where Uncle Phil lives is Bel-Air. In The Fresh Prince of Bel-Air, Philip Banks and his family live in an affluent Los Angeles community, where Will moves after leaving West Philadelphia.

Bel-Air is portrayed as a symbol of wealth, privilege, and polished upper-class life. That setting creates the show's central contrast: Will's street-smart Philadelphia upbringing repeatedly clashes with the Banks family's formal home, private-school world, and professional success. Uncle Phil is a wealthy lawyer who later becomes a superior court judge, making the family's Bel-Air lifestyle part of his larger character story.

A common mix-up is confusing Bel-Air with Beverly Hills, another famous affluent Los Angeles area. The show's title and opening theme specifically identify Bel-Air as the Banks family's neighborhood. The location is fictionalized for comedy, but Bel-Air itself is a real Los Angeles community in the foothills west of Hollywood.
