A Guide to Recognizing Your Saints is a 2006 American drama film based on a 2001 memoir of the same name by author, director, and musician Dito Montiel, which describes his youth in Astoria, New York during the 1980s.

Montiel wrote and directed the film adaptation, which was released in the United States in September 2006 and in Europe in March 2007. The film stars Robert Downey Jr. as Montiel with Shia LaBeouf as a younger Montiel.

The film's narrative jumps frequently between 2005 and flashbacks from 1986 (filmed largely with shaky camera with short shots) with characters occasionally addressing the viewer.
