The 2019–20 Tennessee State Tigers basketball team represented Tennessee State University in the 2019–20 NCAA Division I men's basketball season.

The Tigers, led by second-year head coach Brian Collins, played their home games at the Gentry Complex in Nashville, Tennessee as members of the Ohio Valley Conference (OVC).

They defeated Morehead State in the first round of the OVC tournament before losing in the quarterfinals to Eastern Kentucky.

They accepted an invitation to participate in the 2020 CollegeInsider.com Postseason Tournament (CIT) and were set to host a first-round game.

Since only the top eight teams in the conference qualify for the OVC tournament, tiebreakers left Tennessee State as the No.
