The Secret Policeman's Ball 2008 was a show in the "Secret Policeman's Balls" series of benefit shows for Amnesty International. Like its immediate predecessor, the show was a single-night event at London's Royal Albert Hall, on Saturday 4 October 2008. The 3-hour event was video-taped and a 95-minute television special adapted from the show was broadcast the following day, on Britain's Channel Four. There was also a "cinecast" in which the Royal Albert Hall event was shown live in 35 cinemas in major British cities.
