Hi-de-Hi! is a BBC television sitcom shown on BBC1 from 1 January 1980 to 30 January 1988.

Set in 1959 and 1960 in Maplins, a fictional holiday camp, the show was written by Jimmy Perry and David Croft, who also wrote Dad's Army and It Ain't Half Hot Mum amongst other programmes. The title was the greeting the campers heard and in early episodes was written Hi de Hi. The series revolved around the lives of the camp's entertainers, most of whom were struggling actors and has-beens.

Inspiration for the series were the experiences of Jimmy Perry, one of the programme's writers. After being demobilised from the Army, he was a Redcoat at Butlins in Filey and Pwllheli during the holiday season.

The series gained large audiences and won 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. In 2014, Jimmy Perry confirmed that Hi-de-Hi! would be repeated, and it began a rerun on 2 February 2015 on BBC Two as part of Afternoon Classics, alongside 'Allo 'Allo!, To the Manor Born and Open All Hours. Hi-De-Hi currently repeats on Gold.
