The Academy Award for Best Motion Picture is one of the Academy Awards, awards given to people working in the motion picture industry by the Academy of Motion Picture Arts and Sciences, which are voted on by others within the industry. In the lists below, the winner of the award for each year is shown first, followed by the other nominees. Except for the early years (when the Academy used a non-calendar year), the year shown is the one in which the film first premiered in Los Angeles County, California; normally this is also the year of first release, but it may be the year after first release (as with Casablanca and, if you count its film-festival premiere, Crash). This is the year before the ceremony at which the award is given; for example, a film exhibited theatrically during 2005 was eligible for consideration for the 2005 Best Picture Oscar, awarded in 2006. The number of the ceremony (1st, 2nd, etc.) appears in parentheses after the awards year, linked to the Wikipedia article (if any) on that ceremony.

Each individual entry shows the title followed by the production company, and the producer. When the film was produced anywhere other than the United States, its country and original title, if applicable, are shown in parentheses.

This award was originally called Best Production.
