The 1954 1000 km Buenos Aires was a motor race for sports cars which was held on January 24 at the Autódromo Municipal-Avenida Paz,. It was the opening race of the 1954 World Sportscar Championship and was also the inaugural 1000 km Buenos Aires. The race was won by Giuseppe Farina and Umberto Maglioli, driving a Ferrari 375 MM

The Ferrari 250 MM was a sports racing car produced by Ferrari from 1952 to 1954. After the initial racing successes of the 3.0-litre Colombo V12 engine, introduced in the 250 S one-off, Ferrari produced a serial racing model. It is best recognisable for the distinctive closed berlinetta bodywork by Pinin Farina. The "MM" in its name stood for the Mille Miglia race.
