The team currently plays in the Torneo Federal A, which is the regionalised third division of the Argentine football league system.

San Martín de Mendoza has played 8 seasons at the top level of Argentine football, more specifically in the Torneo Nacional tournaments of 1967, 1969, 1971–74, 1976, 1978.

San Martín's best ever finish was a third position in its zone, achieved in 1974 and 1978.

San Martín was relegated from Primera B Nacional at the end of 2005–06 after losing the playoff against San Martín de Tucumán.

Therefore San Martín was punished with a 10-point deduction, which left the team in the relegation zone.
