The Delaware–Lehigh football rivalry is an American college football rivalry between the Fightin' Blue Hens of the University of Delaware and the Mountain Hawks of Lehigh University. Though the rivalry has been largely dormant since the 1990s, it was contested annually in the 1950s and 1960s, when both universities were members of the Middle Atlantic Conference, and was a marquee small-college fixture in the mid-1970s, when Delaware and Lehigh were two of the top-ranked teams in NCAA Division II.
