The Argentine Athletics Championships is an annual outdoor competition in the sport of athletics that is organised by the Argentine Athletics Confederation which serves as the national championship for Argentina. It was first held in 1920 as a men only event and women's events were added from 1939 onwards. Most of the winners have been Algerian nationals, though a small number of invited foreign athletes have won events at the competition. In the period 1956 to 1960 two national championships were held, one by the Argentine Athletics Confederation and the other by the Argentine Athletics Federation. These are distinguished as "C" and "F" in the below lists.[1]
