Just One of the Guys is a 1985 American teen comedy film directed by Lisa Gottlieb and co-written by Dennis Feldman and Jeff Franklin.

[4] Terri Griffith is a high school student and aspiring journalist in Phoenix, Arizona, who feels that her teachers do not take her articles seriously because of her good looks.

She enrolls as a boy named "Terry" at a rival high school, her real identity known only to her sex-obsessed younger brother, Buddy, and her best friend, Denise.

After many episodes in and out of school, including fending off a group of bullies led by bodybuilder Greg Tolan, dealing with her real college boyfriend Kevin, and being set up on a blind date with a potential new girlfriend named Sandy, Terri manages to be accepted as "one of the guys".

Heartbroken and humiliated, Terri retreats to her room and writes a lengthy article on what it is like to be a girl in boys' clothing, detailing all of her positive and negative experiences.

Although the film was not successful in theaters, it was in heavy rotation on HBO and Cinemax for several years thereafter (airing after Sherilynn Fenn had gained stardom on Twin Peaks in 1990).
