The 1958 Argentine Grand Prix was a Formula One motor race held on 19 January 1958 at Autodromo Municipal Ciudad de Buenos Aires Circuit.

The race was won by British driver Stirling Moss in Rob Walker's privately entered Cooper T43.

Moss took his seventh Grand Prix victory by 2.7 seconds over Italian driver Luigi Musso (Ferrari 246 F1).

The car's four stud wheels would take almost two laps to complete a tyre change, much slower than their Ferrari and Maserati rivals.

By lap ten Juan Manuel Fangio had taken the lead in the Scuderia Sud Americana entered Maserati 250F and Moss had worked his way forward into second position as the pitstops began for the heavier Italian built cars.
