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 toughest arenas in the country for opposing players to play in. The arena is named for Clifton N. (Pat) McArthur, U. S. Congressman and Oregon student-athlete and the school's first student body president.

Its unique and antiquated structure has the fans on top of the court. The maple floor bounces under the weight of the student section that surrounds the court. In 2001 Sporting News named it "best gym in America". For its history, character, and atmosphere, sports writer and arena researcher Bill Kintner named McArthur Court in his top five of college basketball arenas in America. He notes that McArthur Court "is a building that will give you chills even if there is no game being played."

Until it was replaced in 2011, it was the second oldest on-campus arena still in use, after Fordham University's Rose Hill Gym. McArthur Court saw its first game on January 14, 1927, a 38–10 Oregon victory over Willamette University. Among its finest moments are two upsets over #1 UCLA in the mid-1970s and another upset of the top-ranked Bruins on January 6, 2007. An undefeated home season in 2001–02 propelled the Ducks to the "Elite Eight" in the NCAA Tournament. 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.

Women began playing in 1974 and played their first game at McArthur Court on January 23, 1974, against Southern Oregon University. Mac Court is also home to the OSAA high school 5A and 6A boys' basketball championships.
