The Bell H-13 Sioux is an American single-engine light helicopter built and produced by Bell Helicopter for the military and licence-produced by Westland Aircraft for the British military as the Sioux AH.1 and HT.2. It was the first helicopter to be certified for civil use. The H-13 Sioux is named after the epynomous Native American ethnic group.
