The 1998 Argentine Grand Prix (formally the XXI Gran Premio Marlboro Argentina) was a Formula One motor race held at Autódromo Oscar Alfredo Gálvez, Buenos Aires, on 12 April 1998.

The 72-lap race was won by Michael Schumacher for the Ferrari team, from a second position start.

At the start of the race, Michael Schumacher was caught out by Mika Häkkinen, while David Coulthard maintained his first place.

Schumacher's plan proved to be the right one, as he emerged in front following his second stop, after Häkkinen lost time behind Heinz-Harald Frentzen.

Coulthard was slowed by gearbox problems and lost further ground when he tangled with Jacques Villeneuve, putting the Canadian out, while the Scot collected the solitary point for sixth place behind Häkkinen, Eddie Irvine, Alexander Wurz, and Sauber's Jean Alesi.
