McArthur Court is a basketball arena located on the campus of the University of Oregon in Eugene and the former home of the Oregon Ducks men's and women's basketball teams, replaced in 2011 by Matthew Knight Arena.

The arena is named for Clifton N. (Pat) McArthur, U. S. Congressman and Oregon student-athlete and the school's first student body president.

"[6] The arena was funded by a $15 fee imposed by the Associated Students of the University of Oregon and the mortgage papers were burned as part of a public ceremony after the building was completely paid for.

[7] Until it was replaced in 2011, it was the second-oldest on-campus arena still in use, after Fordham University's Rose Hill Gym.

Players to call the court home over the years include Ron Lee, Greg Ballard, Blair Rasmussen, Terrell Brandon, Fred Jones, Luke Ridnour, Luke Jackson, Malik Hairston, and Aaron Brooks.
