The 1918 Michigan Wolverines football team represented the University of Michigan in the 1918 Big Ten Conference football season. The team's head football coach was Fielding H. Yost in his 18th season with the program. The 1918 team played in a season shortened by World War I travel restrictions and the 1918 flu pandemic. They shared the Big Ten Conference championship with Illinois and finished with a perfect record of 5–0, outscoring opponents 96 to 6. Although no formal mechanism existed in 1918 to select a national champion, the 1918 Michigan team was retroactively selected as the national champion by the Billingsley Report and a co-national champion with Pittsburgh by the National Championship Foundation. The Wolverines played their home games at Ferry Field.
