Head of the Class is an American sitcom television series that ran from 1986 to 1991 on the ABC television network.The series follows a group of gifted students in the Individualized Honors Program (IHP) at the fictional Millard Fillmore High School in Manhattan, and their history teacher Charlie Moore (Howard Hesseman). The program was ostensibly a vehicle for Hesseman, best known for his role as radio DJ Dr. Johnny Fever on the sitcom WKRP in Cincinnati (1978–1982). Hesseman left Head of the Class in 1990 and was replaced by Scottish comedian Billy Connolly (in his first major American production) as teacher Billy MacGregor for the final season. After the series ended, Connolly appeared in a short-lived spin-off titled Billy.

The series was created and executive produced by Richard Eustis and Michael Elias. Elias had previously worked as a substitute teacher in New York City while hoping to become an actor.

A revival of the series was ordered and co-produced by Bill Lawrence's Doozer and Warner Horizon Scripted Television. It was released on HBO Max.
