1966 ICF Canoe Sprint World Championships

The 1966 ICF Canoe Sprint World Championships were held in the East Berlin suburb of Grünau in East Germany. This event was held under the auspices of the International Canoe Federation. From 19 to 21 August, competitors used the regatta course on the Langer See that had previously been used for the canoeing and rowing events at the 1936 Summer Olympics.

The men's competition consisted of four Canadian (single paddle, open boat) and nine kayak events. Three events were held for the women, all in kayak. This was the first championships which had one competitor or team per nation per event, a rule that continues.

It was also the seventh championships in canoe sprint.
