Barely Legal is the name of an adult magazine targeted primarily at heterosexual men. It features explicit photos of naked young women, all of whom are at least 18 years old. The models are selected and photographed to emphasize their youth. As with most pornographic magazines of this type, many of the women featured in the magazine are shown using sex toys, spreading their legs out wide so that their vagina shows, spreading their buttocks to show their anus, urinating, masturbating, putting their fingers in their vagina or vulva, pulling open their labia minora, or touching their clitoris. Some of the women appear to be moaning in their pictures as well. The pictorials do not feature simulated or hardcore sex with men; models either appear by themselves or in groups of two or more women. Each issue, one of the models is singled out as the "Barely Legal Teen Queen of the Month", whose pictorial includes the centerfold.

Each pictorial is accompanied by what purports to be a profile of or interview with the model, although a disclaimer in the fine print of each issue's indicia clearly states that this text is fiction and likely has little to no basis in reality. These profiles tend to pander to the readers' fantasies by portraying the models as somewhat naive and sexually inexperienced, but curious and eager to start satisfying their sexual appetites now that they have reached the age of consent. In addition to the pictorials, most issues feature a letters column with responses (attributed to the models) to readers' comments about the magazine, a few reviews of "legal teen"-themed adult videos, and a sexually explicit short story written in the first person from the point of view of an 18-year-old woman, usually describing her experience of some sort of sexual awakening.

Barely Legal is published thirteen times per year by Larry Flynt's LFP, Inc., and is sometimes marketed as Hustler Barely Legal. Hustler Video also produces a Barely Legal line of videos.

Less frequently, LFP publishes Barely Legal Hardcore magazine, which depicts young women engaging in hardcore sex.

In the movie Sideways, the school teacher played by Paul Giamatti is portrayed as being a regular reader of Barely Legal. A scene in which he buys the magazine at a convenience store contained an error: the store has both the October and November issues for 2003 on display, but when Giamatti's character requests "the new one" he is handed the October issue instead.
