Stephen F. Austin Lumberjacks and Ladyjacks

The Stephen F. Austin Lumberjacks and Ladyjacks are composed of 16 teams representing Stephen F. Austin State University (SFA) in intercollegiate athletics. Stephen F. Austin teams participate in Division I as a member of the Southland Conference (SLC), having rejoined that conference on July 1, 2024 after three years in the Western Athletic Conference (WAC). The football team competes in the NCAA Division I Football Championship Subdivision (FCS, formerly known as Division I-AA) for football in the SLC. The only SFA sport not sponsored by the SLC is women's bowling, which competes in Conference USA (CUSA).

On July 1, 2021, SFA was one of five institutions announced as future members of the WAC, alongside three other Southland members from Texas (Abilene Christian, Lamar, Sam Houston) plus Big Sky Conference member Southern Utah. Initially, all five schools were to join in July 2022, but the entry of SFA and the other Texas schools was moved to 2021 after the Southland expelled its departing members. Because the WAC does not sponsor beach volleyball, SFA joined the Atlantic Sun Conference (then officially known as the ASUN Conference) for that sport. After the 2022 season, SFA moved beach volleyball to the Sun Belt Conference.

SFA football played the 2021 and 2022 seasons in a football-only alliance between the WAC and the ASUN. After the 2022 season, the WAC and ASUN fully merged their football leagues under the new identity of United Athletic Conference.

On July 1, 2024, SFA officially rejoined the SLC for all sports except women's bowling, which remains in Conference USA.
