The Oregon Student Association (OSA), a non-profit organization, was established in 1975 to represent, serve and protect the collective interests of students in post-secondary education in the U.S. state of Oregon.

[1] OSA focuses on issues such as tuition, financial aid, and student rights.

The General Assembly is the main decision-making body of the Oregon Student Association.

From the GA, a small group of students is elected to be the Executive Committee which is responsible for the day-to-day leadership of OSA.

Each of OSA's three boards (The Board of Governors, The Oregon Students of Color Coalition, and the Oregon Student Equal Rights Alliance) consist of two student voting members from each fee-paying member campus: The OSA supports House Bill 4163 in the 82nd Oregon Legislative Assembly, require the Oregon Higher Education Coordinating Commission to establish a grant program to expand the scope and community reach of college access and success programs.
