The 2020–21 NCAA Division I men's ice hockey season began on November 14, 2020, and concluded with the Frozen Four on April 10, 2021. Due to the cancellation of the previous year's tournament due to COVID-19 pandemic, this was the 73rd season in which an NCAA ice hockey championship was held, and was US college hockey's 127th year overall.
