The North American Interfraternity Conference is an association of intercollegiate men's social fraternities that was formally organized in 1910, although it began at a meeting at the University Club of New York on November 27, 1909. The power of the organization rests in a House of Delegates in which each member fraternity is represented by a single delegate. However, the group's executive and administrative powers are vested in an elected board of directors consisting of nine volunteers from various NIC fraternities. Headquartered in Indianapolis, Indiana, the NIC has a small professional staff.

Fraternities and sororities exist for high school students as well as college students. Like their college counterparts, most have Greek letter names.

Many of the local chapters of these national fraternities were not tied to individual high schools but were instead area-based, often drawing membership from multiple high schools in a given area.
