Hi-de-Hi! is British sitcom series, created by Jimmy Perry and David Croft, and produced for the BBC. The programme initially aired with a pilot on 1 January 1980, before being greenlighted for a full series, with around eight series aired from 26 February 1981 to 30 January 1988, and starring Paul Shane, Su Pollard, Jeffrey Holland and Ruth Madoc.

The series, inspired by Perry's time serving as a Redcoat at Butlins in Filey and Pwllheli, takes place towards the end of the traditional British holiday period of the 1950s, within a holiday camp in Essex run by the fictional company Maplins - based upon the real-life holiday camp groups that operated during that period. The episodes themselves focus on the lives of the camp's entertainers and staff, most of whom are struggling actors and has-been entertainers, who frequently greet campers with the titular phrase "Hi-de-Hi!"

The programme proved popular from its launch, gaining large audiences during its broadcast; its popularity helped it to win a BAFTA as Best Comedy Series in 1984. In a 2008 poll on Channel 4, Hi-de-Hi! was voted the 35th most popular comedy catchphrase. By 2015, the series began receiving repeats, initially with the BBC alongside other sitcom classics by Croft and Perry, and subsequently moved onto being repeated on Gold
