9 to 5 (titled Nine to Five in the opening credits) is a 1980 American comedy film directed by Colin Higgins, who wrote the screenplay with Patricia Resnick, and starring Jane Fonda, Lily Tomlin, Dolly Parton, Dabney Coleman, Elizabeth Wilson, and Sterling Hayden. It tells the story of three working women who live out their fantasies of getting even with and overthrowing their company's autocratic, "sexist, egotistical, lying, hypocritical bigot" vice president.

The film grossed over $103.9 million. As a star vehicle for Parton—already established as a successful musician—it launched her permanently into mainstream popular culture. A television series based on the film ran for five seasons in the 1980s, and a musical stage adaptation with new songs written by Parton opened on Broadway in 2009.

9 to 5 is 74th on the American Film Institute's "100 Funniest Movies" and has a 69% approval rating on review aggregator website Rotten Tomatoes. The film is considered a cult classic.
