The Jacksonville Dolphins are the intercollegiate athletics teams that represent Jacksonville University, located in Jacksonville, Florida. The Dolphins participate in NCAA Division I athletics, and are primarily members of the ASUN Conference. Some teams in sports that are not sponsored by the ASUN play in other conferences; specifically, the men's and women's rowing teams are in the Metro Atlantic Athletic Conference. The men's lacrosse team had played in the Southern Conference (SoCon) from 2015 to 2022, but that sport will return to the ASUN for the 2023 season.
