One Night Only are a British Indie rock band from Helmsley, North Yorkshire formed in 2003.

One Night Only formed in summer 2003, consisting initially of Mark Hayton, Daniel “Pob” Parkin, Sam “Gunner” Ford and Kai "Kai" Smith. The band did not have a vocalist until George Craig, a friend of Ford's brother, joined in a practice. He was asked to be the vocalist, but insisted on playing guitar as well. Smith then left the band.Contrary to some reports, they did not start out as a Beatles cover band — they initially played songs by bands such as Blink-182, New Found Glory and The Beatles, as well as some of their own material.

The name, One Night Only, came about when asked to play a gig. They did not have a name at the time and so came up with One Night Only, intending the title to, literally, last for only one night, however the name stuck to this day. They performed their first gig on 12 December 2003 in Kirkbymoorside Memorial Hall,which became a popular venue in their early days. In 2005, keyboardist Jack "Fish" Sails joined the bandThe band has appeared on The Friday Night Project, performing their third single “It's About Time”. George Craig also appeared on Hollyoaks, performing an acoustic version of the same song.

In 2007, the band toured with Milburn and The Pigeon Detectives. Their first headline tour started in January 2008, ending in March. Their biggest headline tour to date took place in Autumn 2008. They also played at several festivals, including Isle of Wight, Oxegen and Glastonbury. The band have done a subsequent tour, supported by Northern Irish rock trio General Fiasco, Onlookers and other bands, at venues such as the Lincoln Engine Shed and The Astoria.

They started their latest tour on 15 June 2010.
