The 2021 NCAA Division I FCS football season, part of college football in the United States, was organized by the National Collegiate Athletic Association (NCAA) at the Division I Football Championship Subdivision (FCS) level.
After the prior season was impacted by the COVID-19 pandemic in the United States, resulting in some conferences canceling their seasons and significant rescheduling by other conferences, the 2021 season returned to its traditional fall scheduling. The season ended with a single-elimination tournament, with the championship game held on January 8, 2022 at Toyota Stadium in Frisco, Texas. North Dakota State won its ninth championship in eleven seasons, defeating Montana State, 38-10, for the title.
