Seattle University is a private, co-educational Roman Catholic university in the United States. Located on Seattle, Washington's First Hill, it was founded in 1891 as the School of the Immaculate Conception by the Society of Jesus. Today, Seattle University is one of 28 member institutions of the Association of Jesuit Colleges and Universities.

Seattle University was founded by Father Victor Garrand and Father Adrian Sweere in downtown Seattle. It served as both a high school and college. In 1893, construction began on the First Hill campus. The school moved to First Hill in 1898 and changed its name to Seattle College, at which point the high school became a separate institution now known as Seattle Preparatory School. In 1909, the college awarded its first bachelor's degrees. Seattle College changed its name to Seattle University in 1948.

The university includes the College of Arts and Sciences, the Albers School of Business and Economics, the School of Education, the School of Law, Matteo Ricci College, the School of Nursing, the School of Science and Engineering, and the School of Theology and Ministry, and awards bachelor's, master's, and J.D. degrees.

The School of Law was founded in 1972 as part of the University of Puget Sound in Tacoma, Washington. Twenty-one years later UPS and Seattle University agreed on a transfer of the law school to Seattle University; in August 1994 the transfer was completed, and the school physically moved to Seattle in 1999.

The school's sports teams are the Redhawks, and participate in the NCAA's Great Northwest Athletic Conference.
