The 14 Hour Technicolor Dream was a concert held in the Great Hall of the Alexandra Palace, London, on 29 April 1967. The fund-raising concert for the counterculture paper International Times was organised by Barry Miles, John "Hoppy" Hopkins, David Howson, Mike McInnerney and Jack Henry Moore. It was part-documented by Peter Whitehead in a film called Tonite Let's All Make Love in London.

Alexandra Palace is an entertainment and sports venue in North London, situated between Wood Green and Muswell Hill in the London Borough of Haringey. A Grade II listed building, it is built on the site of Tottenham Wood and the later Tottenham Wood Farm. Originally built by John Johnson and Alfred Meeson, it opened in 1873 but following a fire two weeks after its opening, was rebuilt by Johnson. Intended as "The People's Palace" and often referred to as "Ally Pally", its purpose was to serve as a public centre of recreation, education and entertainment; North London's counterpart to the Crystal Palace in South London.
