The Uros (Uru: Qhas Qut suñi) are a pre-Incan people who live on forty-two self-fashioned floating islands in Lake Titicaca Puno, Peru and Bolivia. They form three main groups: Uru-Chipayas, Uru-Muratos and the Uru-Iruitos. The latter are still located on the Bolivian side of Lake Titicaca and Desaguadero River.
