The 2015 North Dakota State Bison football team represented North Dakota State University in the 2015 NCAA Division I FCS football season. They were led by second-year head coach Chris Klieman. The team, which played its 23rd season in the Fargodome, entered the season as the four-time defending national champions. The Bison have been members of the Missouri Valley Football Conference (MVFC) since the 2008 season.
The Bison went 13âÂÂ2 on the season, won their fifth straight MVFC title, and their fifth consecutive NCAA Division I Football Championship, becoming the first-ever NCAA football team to win five straight championships at any level. Yale won six straight college football national championships from 1879 to 1884, before the NCAA was formed.
