Noggin the Nog is a fictional character appearing in a TV series (of the same name, originally broadcast 1959–1965 and 1982) and a series of illustrated books (published 1965–1977), created by Oliver Postgate and Peter Firmin. The TV series is considered a cult classic from the golden age of British children's television. Noggin himself is the simple, kind and unassuming "King of the Northmen" in a roughly Viking-age setting, with various fantastic elements such as dragons, flying machines and talking birds.

Peter Firmin is said to have come up with the name of Noggin after travelling on the London Underground and seeing Neasden tube station, which made him think "Noggin".

Some of the original artwork for the series is on display at the Rupert Bear Museum. The appearance of the characters was influenced by that of the Lewis chessmen in the British Museum.
