The Northern Kentucky River Monsters were a professional indoor football team based in Highland Heights, Kentucky. The River Monsters began play as a charter member of the Ultimate Indoor Football League (UIFL) for its inaugural 2011 season spending one season in the UIFL before reaching an agreement with league management to leave. After a two-year hiatus, the River Monsters returned in 2014 as a member of the South Division of the Continental Indoor Football League (CIFL). The River Monsters played their home games at The Bank of Kentucky Center. On June 6, 2011, it was announced that the UIFL and the River Monsters mutually agreed to part ways, leaving the team free to join another league. However, the UIFL had a lease agreement with the arena, which hampered the likelihood the River Monsters would play in Highland Heights in 2012. The team had been mentioned as a charter member Stadius Football Association in 2012, but that league never got off the ground. The team suspended operations on October 1, 2014.
