Montauk Diaries is an East Hampton holiday diary filmed in the style of Andy Warhol by the US artist, Peter Beard, in 1972. The film was originally shot by the documentarists David and Albert Maysles.

The film was commissioned by Lee Radziwill, the daughter of Jack Bouvier and also the sister of Jackie Kennedy. By far the most interesting part of the film is the family meeting with mother-and-daughter neighbours, Big and Little Edie Bouvier.
Later, the Maysles returned to make a film entirely dedicated to the the eccentric Bouvier women.
