McArthur Court, Historic basketball arena at University of Oregon in Eugene, United States.

McArthur Court is a basketball arena on the University of Oregon campus in Eugene, in the state of Oregon. The seating rises steeply on three levels around the court, placing spectators very close to the floor and giving the building a compact, enclosed feel.

McArthur Court opened on January 14, 1927, when Oregon beat Willamette University 38–10. It was the second-oldest on-campus arena still in use until it was replaced in 2011 by Matthew Knight Arena. Women's basketball began playing there on January 23, 1974, against Southern Oregon University. The arena also hosted the OSAA Class A-1 state tournament from 1947 to 1965.

The name honors Clifton McArthur, the first student body president of the University of Oregon, reflecting the close bond between this building and the campus community. Beyond basketball, the venue has hosted concerts and other large gatherings that became part of student life over the decades.

McArthur Court stands on the University of Oregon campus in Eugene and was replaced in 2011 by Matthew Knight Arena, so it no longer hosts Ducks games. Its steep seating put fans on top of the court, and the student section made the maple floor bounce. Check current campus use before planning a visit.

Construction was largely funded by students, each of whom paid a $15 (about 14 EUR) fee toward the building. When the loan was fully repaid, the university held a ceremony where the mortgage documents were burned to mark the occasion.
