"Fuck the Millennium", sometimes spelled "***K the Millennium", is an electronic protest song that was released as a single in 1997 by 2K (Bill Drummond and Jimmy Cauty, better known as The KLF and The Justified Ancients of Mu Mu). Based upon The KLF's acid house track "What Time Is Love?", it was promoted as a single and released to mark the tenth anniversary of Drummond and Cauty's first collaborations; however, it was also in part intended to mock the notion of the comeback. It remains the only commercial release by the duo since The KLF's 1992 retirement. The single reached #28 in the UK Singles Chart in October 1997.

Drummond and Cauty's campaign to "fuck the millennium" also involved an appearance by 2K at London's Barbican Arts Centre and a number of outlandish proposals to 'commemorate' the millennium under the moniker "K2 Plant Hire". These activities were intended to culminate in the construction of "The People's Pyramid", a 150-foot (46 m)-high structure built from recycled bricks, but the pyramid was never built.

From 1987 to 1992, Bill Drummond and Jimmy Cauty released music under names including The Justified Ancients of Mu Mu (The JAMs) and The KLF. Following a run of five consecutive UK top-five singles, The KLF executed a high-profile retirement from the music business and deleted their entire back catalogue, declaring that "For the foreseeable future, there will be no further record releases from any past, present or future name attached to our activities." Drummond and Cauty's subsequent art project, the K Foundation, disposed of The KLF's earnings, including by burning one million pounds of it, money which was originally provisionally earmarked by the duo for millennial celebrations. Bill Drummond: "Originally we were going to invest the whole lot in some capital growth fund and spend it all on one big event, maybe at the millennium".
