The Virginia Tech–West Virginia football rivalry is an American college football rivalry between the Virginia Tech Hokies and West Virginia Mountaineers. The teams met 53 times between 1912 and 2021, every year from 1973 to 2005, and as conference foes from 1991 to 2003 as members of the Big East Conference. The winner of the game receives the Black Diamond Trophy sponsored by Rish Equipment Company, headquartered in Bluefield, West Virginia. It was introduced in 1997 and was meant to symbolize the Appalachian region's rich coal heritage (the phrase "black diamond" is often used as a term for coal.)
