Office Space is a 1999 American satirical black comedy film written and directed by Mike Judge. It satirizes the office work life of a typical 1990s software company, focusing on a handful of individuals weary of their jobs. It stars Ron Livingston, Jennifer Aniston, Gary Cole, Stephen Root, David Herman, Ajay Naidu, and Diedrich Bader.

Office Space was filmed in Dallas and Austin, Texas. It is based on Judge's Milton cartoon series and was his first foray into live-action filmmaking. The film was Judge's second full-length motion picture release, following Beavis and Butt-Head Do America. It was released in theaters on February 19, 1999, by 20th Century Fox. Its sympathetic depiction of ordinary information technology workers garnered a cult following within that field, but it also addresses themes familiar to white-collar employees and the workforce in general. It was a box office disappointment, making $12.2 million on a $10 million production budget; however, it sold well on home video, and has become a cult film.

Several aspects of the film have become Internet memes. A scene in which the three main characters systematically destroy a dysfunctional printer has been widely parodied. Swingline introduced a red stapler to its product line after the Milton character used one painted in that color in the film. Judge's 2009 film Extract is also set in an office and was intended as a companion piece to Office Space.

Peter Gibbons is a frustrated and unmotivated programmer who works at Texas-based software company Initech. Unable to stand up to his overcritical girlfriend, Anne, he is in love with local waitress Joanna, but is afraid to speak to her. He is friends with co-workers Samir Nagheenanajar, who hates that no one can pronounce his last name, and Michael Bolton, who hates having the same name as the famous singer. Other co-workers include Milton Waddams, a meek collator who mumbles to himself and is mostly ignored by the rest of the office; and Tom Smykowski, a jaded product manager who is routinely scared of being fired. The staff suffers under top-heavy, callous management, especially from vice president Bill Lumbergh, a tedious micromanager who regularly humiliates Milton and makes Peter work almost every weekend. Peter hates Lumbergh but avoids confronting him.

Anne persuades Peter to attend an occupational hypnotherapy session led by Dr. Swanson. Swanson hypnotizes Peter and tells him to feel relaxed and stop caring about his job until he snaps his fingers. However, Swanson suddenly dies of a heart attack before snapping Peter out of it. Peter sleeps soundly through the next day, ignoring phone calls from Lumbergh and Anne, who angrily breaks up with him while confirming his suspicions that she has been cheating on him.

Two business consultants are brought in to help the company downsize, and Peter begins dating Joanna. She works at a chain restaurant where she is required to wear "pieces of flair": buttons allowing employees to "express themselves". Her boss hassles her for not wearing more than the required minimum.

Peter eventually shows up to work and casually disregards office protocol, stealing Lumbergh's parking space, violating the dress code, and removing a cubicle wall that blocks his view out the window. Impressed by Peter's frank insights into Initech's problems, the consultants promote him despite Lumbergh's misgivings; however, they lay off Michael, Samir, and Tom. While attempting to do the same to Milton, they learn that he had already been laid off five years prior but had not been notified and was still receiving his salary due to a payroll glitch. They fix the glitch and stop Milton's salary payments without telling him, while Lumbergh continues to mistreat him by confiscating his beloved red stapler and repeatedly relocating his desk, eventually down to the basement.

Tired of their own mistreatment, Peter, Michael, and Samir decide to take revenge by infecting Initech's accounting system with a computer virus designed by Michael to divert huge numbers of fractions of pennies into a bank account. Peter successfully installs the virus, and on Michael and Samir's last day, he steals a frequently malfunctioning printer, which the three proceed to destroy in a field. They also learn that Tom attempted suicide prior to being laid off, but then changed his mind, and in the process got into an accident that resulted in him winning a large amount of money in damages from a lawsuit. At a party at Tom's house, Peter hears rumors from a colleague that Joanna had slept with Lumbergh. When Joanna confirms this, a heated exchange leads to them breaking up. Frustrated with her job, Joanna quits in response to another lecture about her lack of "flair", giving her boss the middle finger as she does so.
