The Museum of the Moving Image (MOMI) was a museum of the history of cinema technology and media sited below Waterloo Bridge in London. It was opened on 15 September 1988 by Prince Charles and at the time, was the world's largest museum devoted entirely to cinema and television. The museum formed part of the cultural complex on the South Bank of the River Thames. MOMI was mainly funded by private subscription and operated by the British Film Institute. MOMI was closed in 1999, initially on a supposedly temporary basis, and with the intention of its being relocated to Jubilee Gardens nearby. Its permanent closure was announced in 2002.

MOMI was the brainchild of National Film Theatre Controller Leslie Hardcastle. Hardcastle's vision was realised by significant fundraising by then Director of the BFI, Anthony Smith and a development team including David Francis, David Robinson, Charles Beddow (1929-2012), Chief Technical Officer of the National Film Theatre, and the designer Neal Potter.

Smith raised the museum's £15m project costs entirely from private sources.

Interpretation was done through graphics, interactive exhibits, recreated environments, models, six 35 mm film projections using endless loop platters, two 16 mm film projections, two 70 mm projectors, and over 70 LaserDisc players for video playback. There was also a group of six actors dressed in period costume (e.g. a Victorian magic lanternist and a Hollywood director).

A few months before MOMI opened in 1988, the animator Chuck Jones was invited to create a chase sequence directly onto the high walls of the museum. Jones spent several days working on high scaffolding to create the work. At the lowest level on a door was a smaller drawing (not part of the chase) which Jones used to try out the pens.

Animation played an important role in MOMI. Channel Four funded the Channel Four/MOMI animator in residence scheme. Winners of the competition developed a short film in the 'goldfish bowl', a three-meter (10') square glass box; this allowed the public to see the animator's every move. Over forty films were produced and they won many awards worldwide.

Prior to opening, the museum bought Marilyn Monroe's black dress from the 1959 film Some Like It Hot, for £19,800. The event featured on the front pages of many UK newspapers.

There was a busy education department with two education rooms and a small cinema for special events. The museum was available for private hire for corporate events or parties.
