The 1989 Brazilian Grand Prix was a Formula One motor race held at Jacarepaguá, Rio de Janeiro on 26 March 1989. It was the first race of the 1989 Formula One World Championship.
The 61-lap race was won by Englishman Nigel Mansell, driving for Scuderia Ferrari, with Frenchman Alain Prost second for McLaren-Honda and local driver Maurício Gugelmin third in a March-Judd. It was the first time that a car with a semi-automatic gearbox won the race. Mansell claimed that he had booked an early flight home as he did not expect the new Ferrari 640 (which had severe reliability problems in testing and practice sessions before the race) to complete the distance, and during the podium ceremony he cut his hand whilst lifting the trophy.
Missing out in sixth was Alex Caffi in the Dallara, ahead of veteran Piercarlo Ghinzani in the other Osella. Another newcomer, German driver Volker Weidler was eighth in the Rial, with Pierre-Henri Raphanel's Coloni ninth, ahead of Joachim Winkelhock, also competing in Formula One for the first time, in the AGS. Eleventh was the second Zakspeed of Aguri Suzuki, with the Onyx drivers a little way adrift at the bottom of the time sheets, having had little time to test their new car. Stefan Johansson was faster than his Belgian team-mate Bertrand Gachot, the other driver in the session to make his Formula One debut, but was still over seven seconds slower than Brundle's time. Temperatures during Saturday's qualifying practice session were around . Mansell had lacked confidence in the new V12-powered Ferrari's reliability, and as such had booked a flight home which was due to depart at 16:30.
