The fifth series of British talent competition programme Britain's Got Talent was broadcast on ITV, from 16 April to 4 June 2011; due to live coverage of the 2011 UEFA Champions League Final on 28 May, the final audition episode of the series was pushed back a day to avoid clashing with it. As Piers Morgan had departed from the programme the previous year, and the schedule of Simon Cowell made him unable to attend auditions, the producers arranged for Amanda Holden to be joined by David Hasselhoff and Michael McIntyre on the judging panel. Due to Hasselhoff's schedule during filming of the auditions, Louis Walsh stepped in as a guest judge for the sessions he could not attend.

Britain's Got Talent is a televised British talent show competition, and part of the global Got Talent franchise created by Simon Cowell. Presented by Anthony McPartlin and Declan Donnelly, it is produced by both Thames and Syco Entertainment, distributed by Fremantle, and broadcast on ITV every year in late Spring to early Summer. The show was originally intended for production in 2005, but filming was suspended in the wake of a dispute between ITV and the programme's originally planned host. Following the success of America's Got Talent that year, production resumed and the programme eventually premiered on 9 June 2007.
