By 1976 a group of veteran rugby players decided to create a club where to play the sport they loved. On March 3, 1977, Club Argentino de Rugby was founded, with the participation of children from 8 to 12 years old and their parents also collaborating with the project.
At first, they trained in a little square, moving then to a football field rented to the Asociación Cristiana de Jóvenes (Youth Christian Association) and finally in Club Arsenal de Sarandí. Argentino's home games were played in a rented field owned by the Dirección Nacional de Vialidad (the organism that regulates the roads of Argentina), which was located in Ezeiza, Buenos Aires.
The first jerseys were sold in a pharmacy and the administration office worked in a little room of the Círculo Universitario de Avellaneda.
The team promoted to first division in 1987 and 1997 but would be later relegated to a lower category.[2] In 2011 Argentino was relegated to third division.
