2020–21 NCAA Division III football season

The 2020–21 NCAA Division III football season was the component of the 2020 college football season organized by the NCAA at the Division III level in the United States. Due to the COVID-19 pandemic, only a few games were played during the traditional fall season, including the annual Secretaries Cup between Coast Guard and Merchant Marine on November 14, 2020. For other teams that chose to play during the 2020–21 school year, the regular season began on February 6, 2021 and culminated on May 1.

The season concluded with the end of the regular season, as the playoffs and championship game were not held due to the pandemic.
