Which conference does Oregon State belong to?

Oregon State belongs to the Pac-12 Conference, which is a collegiate athletic conference that primarily represents schools located in the western United States. Established in 1915, the Pac-12 has a rich history in various sports, including basketball, where it is known for its competitive programs and notable players. Specifically for Oregon State, it is one of the founding members of the Pac-12 and has a longstanding rivalry with other schools in the conference, particularly with Oregon in the Civil War game. This affiliation provides Oregon State with the opportunity to compete against other prestigious programs, enhancing its visibility and recruiting potential within collegiate athletics.

In contrast, the other options refer to different conferences—Big Ten, SEC (Southeastern Conference), and ACC (Atlantic Coast Conference)—to which Oregon State does not belong, and those conferences have different geographic focuses and member institutions.
