2019 Sun Belt Conference softball tournament

The 2019 Sun Belt Conference softball tournament was held at the Bobcat Softball Complex on the campus of the Texas State University in San Marcos, Texas, from May 8 to May 11, 2019. The tournament used a double-elimination format for the tournament as in past years. Louisiana, the winner of the tournament, earned the Sun Belt Conference's automatic bid to the 2019 NCAA Division I softball tournament.

Seeding
In a change from previous years, the top eight teams (based on conference results) from the conference earned invites to the tournament. The teams were seeded based on conference winning percentage, with the bottom four seeds competing in a play-in round. The remaining four teams then played a two bracket, double-elimination tournament. The winner of each bracket played each other in the championship final.
