The Autódromo de Buenos Aires Oscar y Juan Gálvez[1][2] is a 45,000 capacity motor racing circuit in Buenos Aires, Argentina built in 1952 under president Juan Perón, named Autódromo 17 de Octubre after the date of Loyalty Day until Perón's overthrow.

The 1000 km Buenos Aires sports car event used the Autódromo as well as sections of highway situated near the track from 1954 to 1960.

Formula One used a number of different configurations—the No.2 circuit was used from 1954–1960, the No.9 circuit was used from 1971–1973, and the very fast No.15 layout was used from 1974–1981 which added 2 long straights and a long third corner between the two straights often taken in top gear flat out, which provided an exciting view for spectators, especially when the cars exited the third corner often on the brink of spinning off or crashing at 305 km/h (190 mph).

The twisty No.6 configuration, though using S de Senna instead of Tobogán, was used from 1995–1998, but that version of the circuit was not popular with Formula One.
