The 1966 Dutch Grand Prix was a Formula One motor race held at Zandvoort on July 24, 1966.

It was race 5 of 9 in both the 1966 World Championship of Drivers and the 1966 International Cup for Formula One Manufacturers.

Brabham lapped the field on his way to his second Dutch Grand Prix victory to add to his win in 1960.

British driver, 1962 world champion Graham Hill finished second in his BRM P261, himself a lap ahead of the rest of the field.

Reigning world champion Jim Clark took his first podium finish of the year in his Lotus 33, after duelling with the Brabhams in the early stages, even leading the race and pulling away before suffering a water pump failure that set him back two laps.
