Banco Nación was founded on October 12, 1909, as sports club by employees of Banco de la Nación Argentina, Argentina's state-owned bank. Originally located near the Colegiales railway station, the club moved to its current location on Zufriategui street in 1928.
Banco Nación's rugby team won the URBA Tournament in 1986 and 1989, as well as several rugby sevens tournaments. Hugo Porta, long-time captain of the national team, played in Banco Nación during his entire career; other recognized Pumas, such as Fabián Turnes, Pablo Hacha Dinisio, Fabio Aguja Gómez, and Rodolfo Capeltti began their careers with the team.
On July 14, 1990, Banco Nación defeated England national team in a surprising 29 to 21 victory,[2] being the only club level team to do that in the world. Banco Nación is the only Argentine club to defeat two national teams, having also defeated Canada in 1989.
In 2010 Banco was relegated to the second division, along with Club Pueyrredón.[3] In November, 2011, Banco Nación defeated Hurling Club 31-28 proclaiming second division champion.[4]
In September 2014, Banco Nación returned to the first division (Grupo I) after defeating Universitario (La Plata) by 41-19.[5][6]
In December 2018, Hugo Porta, the most notable rugby player in Banco Nación's history,[7] was elected president of the institution.[8]
