The National Collegiate Box Series (NCBS) was established by the US Box Lacrosse Association (USBOXLA) in 2018. The highly skilled series provides American collegiate players an opportunity to improve their overall lacrosse skillset through box lacrosse, to compete for a national championship, and also increase their chances of one day playing in the National Lacrosse League (NLL).
First formed in 2017, the Colorado Collegiate Box Lacrosse League (CCBLL) predates the formation of the NCBS, joining the series when it was officially launched a year later. In 2018, the Ohio Collegiate Box Lacrosse League (OCBLL) was established with teams based in both Columbus and Cleveland. In 2019, the OCBLL's Rivermen won the inaugural NCBS National Championship beating the CCBLL's Fighting Bison 2 games to 1 at the 2019 USBOXLA Nationals.
In 2020, the NCBS welcomed the Upstate Collegiate Box Lacrosse League (UCBLL) and the Connecticut Collegiate Box Lacrosse League (CTCBLL) in a season that was ultimately cancelled.
The NCBS resumed in 2021 with the addition of the California Collegiate Box Lacrosse League (CACBLL). In 2021, the NCBS National Champions were the CACBLL Royals from San Diego. In 2022 the CACBLL Royals won their second consecutive NCBS Championship. Can they three-peat in 2023?
