The 1987 Portuguese Grand Prix was a Formula One motor race held at Estoril on 20 September 1987.

The race was won by Frenchman Alain Prost, driving a McLaren-TAG, after he started from third position.

Austrian driver Gerhard Berger took pole position in his Ferrari and led for most of the race, until he spun with three laps remaining.
