Guillermo Brown de Puerto Madryn

The club was named in honour of Guillermo Brown who was the Irish-born first admiral of Argentina in the mid 19th Century.

Brown finished at the top of their group in the Torneo Clausura 2006, but failed in the next stage, after being defeated by San Martín de Tucumán in the playoff series (with scores of 0–3 and 2–2).

On May 19, 2012, Brown achieved its greatest professional achievement in football, tying 2–2 at River Plate Stadium against a River Plate with figures such as David Trezeguet, Fernando Cavenaghi and Alejandro Dominguez.
