The 2002 Brazilian Grand Prix was a Formula One motor race held on 31 March 2002 at the Autódromo José Carlos Pace in São Paulo. It was the third round of the 2002 Formula One World Championship. Ferrari's Michael Schumacher won the race from second position. Williams's Ralf Schumacher finished in second and McLaren's David Coulthard was third.

Williams's Juan Pablo Montoya set the fastest lap time in the one-hour qualifying session to start the race from pole position. Michael Schumacher took the race lead at the start, but Montoya smashed his front wing into Schumacher's left-rear wheel while attempting to retake it, eliminating his chances of victory. He held the lead until he let his lighter-fuelled, one-stopping teammate Rubens Barrichello take the lead on lap 14 before retiring three laps later due to a loss of hydraulic pressure. Michael Schumacher therefore retook the race lead and held it for the most of the race, defeating his brother Ralf Schumacher in the final laps to win by 0.588 seconds.
