2018–19 Stephen F. Austin Lumberjacks basketball team

The Lumberjacks were led by third-year head coach Kyle Keller and played their home games at the William R. Johnson Coliseum in Nacogdoches, Texas as members of the Southland Conference.

Since only the top eight teams are eligible to play in the Southland tournament, the Lumberjacks failed to qualify this season.

On May 20, 2020, following the discovery of an administrative error in certifying eligibility for student-athletes, Stephen F. Austin reached an agreement with the NCAA to vacate hundreds of wins across multiple sports from 2013 to 2019, including all 117 men's basketball wins from the 2014–15 to 2018–19 seasons.

They defeated Central Arkansas, Nicholls State, and Southeastern Louisiana to become champions of the Southland tournament.

They received the Southland's automatic bid to the NCAA tournament where they lost in the first round to Texas Tech.
