Core Takeaway: Oregon State University (OSU) is Oregon’s largest public research university, see it here enrolling 38,460 students across its Corvallis campus, OSU-Cascades in Bend, and a nationally recognized online Ecampus. As a land grant, sea grant, and space grant institution, OSU combines world-class research in marine biology, forestry, and agricultural sciences with a mission of accessible education for Oregonians.
Founding and Land Grant Mission
Oregon State University traces its origins to 1856 when it was established as Corvallis Academy. On October 27, 1868, Corvallis College became Oregon’s official land grant institution—the first state support for higher education in Oregon. The institution was officially renamed Oregon State University in 1961.
The land grant mission remains central to OSU’s identity. The university operates 15 agricultural experiment stations and 35 county extension offices across Oregon, extending research and education beyond the main campus. Nearly 21% of new incoming students are first in their families to attend college, reflecting OSU’s commitment to educational opportunity for all Oregonians.
Enrollment and Statewide Reach
Oregon State is the largest university in Oregon for the 12th consecutive year, with total enrollment of 38,460 students in Fall 2025. The student body includes representation from all 36 Oregon counties, all 50 states, and over 100 countries.
Enrollment breaks down across OSU’s locations:
- Corvallis campus: 25,374 students
- Ecampus (online): 11,647 students
- OSU-Cascades (Bend): 1,384 students

Of the nearly 4,900 new freshmen, 57% are from Oregon. Washington sends the highest number of out-of-state students, followed by California, Hawaii, Colorado, and Texas.
International enrollment stands at 2,181 students, maintaining strength despite changing visa guidelines and national trends showing declines in new international students.
