The 1970 Wyoming Cowboys football team represented the University of Wyoming in the 1970 NCAA University Division football season. Led by ninth-year head coach Lloyd Eaton, they were members of the Western Athletic Conference (WAC) and played their home games on campus at War Memorial Stadium in Laramie. The Cowboys had a record of 1–9, and Eaton was reassigned to assistant athletic director. The controversial previous season had concluded with four consecutive losses, all on the road.
