The 1974 Brazilian Grand Prix was a Formula One motor race held at Interlagos on 27 January 1974.

The 32-lap race was won by McLaren driver Emerson Fittipaldi after he started from pole position.

The start of the race was delayed as the track had to be swept clear of broken glass from over-exuberant spectators' celebrations and then Arturo Merzario's engine failed.

The race developed into a classic duel between Fittipaldi and Peterson, the Brazilian taking the lead on lap 16 and the Swede soon having to pit with a puncture (believed to be caused by some glass still left on the track).

It was McLaren's second win of the year, but it was Ferrari who, with Regazzoni, topped the drivers' table - for the first time since March 1971.
