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. Also known as "The Pit" or "Mac Court," it was known as one of the most hostile arenas in the nation. The arena is named for Clifton N. (Pat) McArthur, U. S. Congressman and Oregon student-athlete and the school's first student body president.
