The 2018–19 Tennessee State Tigers basketball team represented Tennessee State University during the 2018–19 NCAA Division I men's basketball season.

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

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

They lost in the first round of the OVC tournament to Eastern Illinois.

On March 21, 2018, head coach Dana Ford left Tennessee State for the head coaching job at Missouri State.
