The Illinois–Missouri football rivalry, also known as the Arch Rivalry, is an American college football rivalry between the Illinois Fighting Illini football team of the University of Illinois and Missouri Tigers football team of the University of Missouri. Both schools consider it a friendlier, secondary rivalry compared to their other rivalries like the Border War and Northwestern, but it still generates interest from students and alumni, especially those in and around Greater St. Louis. Both schools have considerable alumni from the area.
