Oklahoma State University (OSU)

A land-grant institution with more than 35,000 students across a five-campus system, we've graduated more than 264,000 students to serve the state of Oklahoma, the nation and the world.

Knowledge that improves lives and strengthens communities

Science, engineering and humanities research takes place in every college on our campuses, and our Center for Health Sciences in Tulsa. Oklahoma State research is in lock-step with its land-grant legacy. Research at OSU, a Carnegie R1 research university, is relevant, accessible and beneficial — whether it’s exploring basic scientific questions or applied concepts that directly impact lives.

Since 1890

OSU has grown to become a premier modern land-grant university.

Founded on Dec. 25, 1890 as Oklahoma Agricultural and Mechanical College, OSU's land-grant mission is to make a college education more accessible. Our roots are set in a rich tradition, and our actions are guided by the Cowboy Code.
