The 2012 Appalachian State Mountaineers football team represented Appalachian State University in the 2012 NCAA Division I FCS football season. They were led by 24th-year head coach Jerry Moore and played their home games at Kidd Brewer Stadium. They were a member of the Southern Conference. They finished the season 8–4, 6–2 in SoCon play to share the conference championship with Georgia Southern and Wofford.
