2018–19 Southeast Missouri State Redhawks men's basketball team

The 2018–19 Southeast Missouri State Redhawks men's basketball team represented Southeast Missouri State University during the 2018–19 NCAA Division I men's basketball season. The Redhawks, led by fourth-year head coach Rick Ray, played their home games at the Show Me Center in Cape Girardeau, Missouri as members of the Ohio Valley Conference. They finished the season 10–21 overall, 5–13 in OVC play, finishing in 11th place. Only the top eight teams can play in the OVC tournament, so the Redhawks did not qualify this season.
