South Dakota Circuit is a permanent motor racing track in Timehri, Guyana.
The circuit was opened in 1956 under British rule as a permanent venue for motorcycle racers, who had previously been using No.
The track was formed from a former World War II airstrip used by the Americans during the North Africa campaign, and the circuit's name was taken from the military aircraft of the same name.
The circuit played host to a variety of Caribbean car and motorcycle championships, with the two-wheeled discipline in particular bringing in British teams and riders well into the 1970s.
As a result of the oil crises of the 1970s and the increasingly socialist policies of Prime Minister Forbes Burnham, racing entered a dormant period in the country in the mid-1970s and only restarted in 1988.
