An Officer and a Gentleman is a 1982 American romantic drama film directed by Taylor Hackford from a screenplay by Douglas Day Stewart, and starring Richard Gere, Debra Winger and Louis Gossett Jr. It tells the story of Zack Mayo (Gere), a United States Navy Aviation Officer Candidate who is beginning his training at Aviation Officer Candidate School. While Zack meets his first true girlfriend during his training, a young "townie" named Paula (Winger), he also comes into conflict with the hard-driving Marine Corps Gunnery Sergeant Emil Foley (Gossett) training his class.

Its title is an old expression from the Royal Navy and later from the U.S. Uniform Code of Military Justice's charge of "conduct unbecoming an Officer and a Gentleman" (from 1860).

The film was commercially released in the U.S. on August 13, 1982. It was well received by critics, with a number calling it the best film of 1982. It also was a financial success, grossing $190 million against a budget that was between $6-$7 million. Gossett won the Academy Award for Best Supporting Actor for the film, making him the first Black male to do so, as well as a Golden Globe Award. The film also received Oscar nominations for Best Actress (for Debra Winger), Best Original Screenplay, Best Film Editing, Best Original Score and Best Original Song (for "Up Where We Belong").
