The Appalachian State–Georgia Southern football rivalry, also known as Deeper Than Hate, is a college rivalry between the Mountaineers of Appalachian State University in Boone, North Carolina, and the Eagles of Georgia Southern University in Statesboro, Georgia.

[2][3] Despite being located in separate states, the two universities have similar academic profiles, both having developed from teachers' colleges, and having enrollments of approximately 20,000.

In addition, both Appalachian and Georgia Southern historically held a very strong presence during their time in the Division I Football Championship Subdivision, having combined to win nine national championships, four Walter Payton Awards, and two Buck Buchanan Awards.

On March 27, 2013, both schools were invited to join the Sun Belt Conference of the Football Bowl Subdivision (FBS) beginning in 2014.

The makings of the rivalry truly began when the Mountaineers beat the Eagles in the quarterfinals of the 1987 I-AA Playoffs.
