The 1966 British Grand Prix was a Formula One motor race held at Brands Hatch on 16 July 1966.

The race, the first of the new three-litre engine regulation era where starters reached 20 cars, was won for the third time by Australian driver Jack Brabham in his Brabham BT19, his second win in succession after winning the French Grand Prix two weeks earlier.

The pair finished a lap ahead of third placed British driver Graham Hill in his BRM P261.

Ferrari did not participate in this Grand Prix weekend to honour a metalworkers strike in Italy.

Brabham duly led home teammate Hulme, Hill, Clark, Rindt and Bruce McLaren.
