The Rivalry is an American college football rivalry game played by the Lafayette Leopards football team of Lafayette College and the Lehigh Mountain Hawks football team of Lehigh University. It is the most-played football rivalry in the nation and the longest uninterrupted annual rivalry series. As of 2015, "The Rivalry" has been played 151 times since 1884 with only a single interruption in 1896. The college's football teams met twice annually (except 1891, when they played three games, and 1896, when they did not play at all) until 1901. The two institutions are located seventeen miles apart in the Lehigh Valley in eastern Pennsylvania. Though primarily alluding to football, "The Rivalry" pertains to a meeting between the two schools in all sports and other endeavors.
