Slacker is a 1990 American comedy drama film written, produced, and directed by Richard Linklater, who also stars in it. Filmed around Austin, Texas, the film follows an ensemble cast of eccentric and misfit locals throughout a single day. Each character is on screen for only a few minutes before the film picks up someone else in the scene and follows them.

Slacker premiered at the USA Film Festival on April 21, 1990, and was released in the United States on July 5, 1991, by Orion Classics. The film received positive reviews from critics and grossed over $1 million against a production budget of $23,000. In 2012, Slacker was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
