The Bellarmine Knights Men's Lacrosse team is a college lacrosse team that represents Bellarmine University in Louisville, Kentucky, United States. The school has been an all-sports member of the ASUN Conference since 2020, but men's lacrosse spent the 2021 season as an associate member of the Southern Conference (SoCon), in which it had competed since the 2015 season. With the reinstatement of ASUN men's lacrosse competition for the 2022 season, Bellarmine moved that sport to its full-time conference home.
