Triangle was a BBC Television soap opera in the early 1980s, set aboard a North Sea ferry which sailed from Felixstowe to Gothenburg and Gothenburg to Amsterdam. A third imaginary leg existed between Amsterdam and Felixstowe to justify the programme title, but this was not operated by the ferry company. The show ran for three series before being cancelled, but is still generally remembered as "some of the most mockable British television ever produced". The scripts involved clichéd relationships and stilted dialogue, making the show the butt of several jokes - particularly on Terry Wogan's morning Radio 2 programme - which caused some embarrassment to the BBC.

In 1992, the BBC screened TV Hell, an evening of programming devoted to the worst television had to offer, and the first episode of Triangle was broadcast as part of the line-up.

The ferry used in the first series was the Tor Line's MS Tor Scandinavia. In the second and third series this was replaced by the DFDS vessel Dana Anglia probably because she had a less intensive schedule and the longer time she spent in port made on-board filming easier.
