It most often refers to the athletic rivalries between the Duke Blue Devils and North Carolina Tar Heels athletic teams . The North Carolina--Duke rivalry is fierce, particularly in men's college basketball . It is considered one of the most intense rivalries in all of US - sports: a poll conducted by ESPN in 2000 ranked the basketball rivalry as the third greatest North American sports rivalry, and Sports Illustrated on Campus named it the #1 "Hottest Rivalry" in college basketball and the #2 rivalry overall in its November 18, 2003 issue . The intensity of the rivalry is augmented by the proximity of the two universities--they are located only ten miles apart along U.S. Highway 15--501 (also known as Tobacco Road) or eight miles apart in straight - line distance . In addition, both Duke and North Carolina are considered highly prestigious universities, which, coupled with their vastly different funding structures and cultures--North Carolina is a public school while Duke is private--contributes to the ferocity of the rivalry .
