All the Boys Love Mandy Lane is a 2006 American slasher film directed by Jonathan Levine and starring Amber Heard, Michael Welch, Whitney Able, and Anson Mount. The plot centers on a group of popular high schoolers who invite an attractive outsider, Mandy Lane, to spend the weekend at a secluded ranch house, where they are followed by a merciless killer.

Originally completed in 2006, the film premiered at a number of film festivals throughout 2006 and 2007, including the Toronto International Film Festival, Sitges Film Festival, South by Southwest, and London FrightFest Film Festival. It received a theatrical release in the United Kingdom on February 15, 2008. All the Boys Love Mandy Lane received mixed reviews from critics, with some dismissing the film as "bogus and compromised", and others praising its exploitation film aesthetic and likening its cinematography to the early work of Terrence Malick and Tobe Hooper.

Despite its international attention, the film remained unreleased in the United States for over seven years after it was completed; this was due to complications with its distributor, Senator Entertainment, which went bankrupt shortly after purchasing the film from The Weinstein Company. On March 8, 2013, it was announced that The Weinstein Company had re-acquired the rights to theatrically release the film in the United States. The film became available through video on demand in September 2013, and was given a limited theatrical release on October 11, 2013, through a joint contract between Senator Entertainment and Weinstein's subsidiary label Radius-TWC.
