The team was founded on August 28, 1928 and less than a year later it would join the Argentine Rugby Union to play at the third division, competing with 22 teams.
The club's name was chosen as a tribute to the Martín Fierro, the most renowned poem of the "Gauchesco" literature in Argentina. Martín Fierro (the character) is described by the author, José Hernández as a "matrero" ("smart", "clever" in English) gaucho. The election of the club name is also related to the place where it was founded: Morón (today a populous city of the Greater Buenos Aires) was an uninhabited land by the time and some battles for the independence had been fought there in the past.[2]
In 2011 Los Matreros was relegated to second division after finishing 11th in Zona Reubicación.
