2019–20 Missouri Valley Conference men's basketball season

The 2019–20 Missouri Valley Conference men's basketball season began with practices in October 2019, followed by the start of the 2019–20 NCAA Division I men's basketball season on November 5, 2019. Conference play began in late December 2019 and concluded in March with the Missouri Valley Conference tournament at Enterprise Center in St. Louis, Missouri.

Northern Iowa captured the regular season title at 14–4.

Bradley defeated Valparaiso in the championship game to win the Missouri Valley Conference tournament and thereby would have received the conference's automatic bid to the NCAA tournament.

Northern Iowa, by virtue of winning the regular season title, but not winning the conference tournament, would have received the conference's automatic bid to the National Invitational tournament.

All subsequent postseason tournaments were canceled due to the COVID-19 pandemic.

Changes
On March 6, 2019, Southern Illinois head coach Barry Hinson resigned. He finished with a seven-year record of 116–106. The school announced on March 20 that former Loyola-Chicago associate head coach (and Saluki alumnus) Bryan Mullins had been named head coach.
