2019–20 NCAA Division I men's basketball season

The 2019–20 NCAA Division I men's basketball season began on November 5, 2019. The first tournament was the 2K Sports Classic and the season concluded prematurely on March 12, 2020. The 2020 NCAA Division I men's basketball tournament was scheduled to end at Mercedes-Benz Stadium in Atlanta, Georgia, on April 6, 2020, but was ultimately canceled. All other postseason tournaments were canceled as well. Practices officially began in late September.

On March 12, 2020, the NCAA announced that all remaining winter and spring championships for both men's and women's sports were canceled due to the COVID-19 pandemic. It was the first cancellation in the NCAA Division I men's basketball tournament history. The NCAA did not name an official national champion after the tournament was canceled.

Kansas finished first in both major polls but has yet to claim a national championship for the season.
