The 1987 Mexican Grand Prix was a Formula One motor race held at Autódromo Hermanos Rodríguez in Mexico City on 18 October 1987. It was the fourteenth race of the 1987 Formula One World Championship.

The race was divided into two heats after British driver Derek Warwick crashed his Arrows A10 heavily exiting the high-speed Peraltada corner on lap 31 after a rear suspension failure; the Arrows car's rear suspension was weakened by Satoru Nakajima crashing his Lotus-Honda straight into the back of Warwick's car at the end of the main straight earlier in the race. The results of the first 30 laps were combined with the results of the second race of 33 laps to create a combined result.

The race was won by British driver Nigel Mansell driving a Williams FW11B. Mansell's combined time over the 63 laps was 26 seconds faster than his Brazilian teammate Nelson Piquet. Piquet actually took the chequered flag first at the end of the second heat, but Mansell's lead over Piquet at the time of Warwick's accident was substantially larger.

It was Mansell's sixth and last Grand Prix victory for the 1987 season. Riccardo Patrese finished third driving a Brabham BT56. It was Patrese's best result since finishing third in the 1984 Italian Grand Prix.
