The OSU campus is protected by a campus police agency consisting of 32 sworn officers, 10 support persons, and 14 part-time persons. The agency is operated and available 24 hours a day, 365 days a year. Authority of the sworn officers is derived from state statutes, which allow for full police powers on OSU property.

In addition, by agreement with the City of Stillwater, campus police and city police enjoy an excellent working relationship. All campus police officers undergo an extensive selection process and meet state mandated training requirements.
