Beta Theta Pi (ΒΘΠ), commonly known as Beta, is a North American social fraternity that was founded in 1839 at Miami University in Oxford, Ohio. One of North America's oldest fraternities. Beta Theta Pi is the oldest of the three fraternities that formed the Miami Triad, along with Phi Delta Theta and Sigma Chi.

The five core values espoused by Beta Theta Pi are cultivation of intellect, responsible conduct, mutual assistance, integrity and trust. These are the underpinnings for their mission statement to "develop men of principle for a principled life." In 1879, Beta Theta Pi became the first college fraternity to publish its constitution. The fraternity continues to guard certain secrets about membership. Similar to other fraternities, Beta Theta Pi's code emphasizes international fellowship, cultural development and cooperation.
