Hillary Norman "Norm" Peterson was a character on the American television show Cheers, portrayed by George Wendt. Norm's real first name was revealed to be Hillary, named after his grandfather.

Norm enters the show as an accountant, though later becomes unemployed and eventually a housepainter. Norm was revealed to be an accomplished interior decorator and beer taster (capable of spotting a bad vat in a factory by drinking a single bottle). Ironically, even when unemployed, Norm is the bar's best customer. Numerous jokes are made about the enormousness of Norm's tab at Cheers (e.g., several large binders are shown as being just a portion of it).

Norm's best friend is postman and fellow barfly Cliff Clavin.

Norm's entrance into the bar is a running gag on Cheers, typically beginning with a welcome by the bar crowd followed by a joke from Norm. A typical entrance went:

Norm enters
Norm: Afternoon, everybody!
Customers: NORM!
Coach: How's life treating you Norm?
Norm: Like he caught me in bed with his wife.
