Tiriós Airport (ICAO: SBTS) is a small general aviation airstrip located in Aldeia Tiriós, a remote indigenous village in the state of Pará, northern Brazil, near the border with Suriname. The facility serves as the primary air access point for the Tiriyó (Tiriyó) indigenous people, who inhabit one of the most isolated regions of the Brazilian Amazon. The airstrip supports essential supply flights, medical missions, and government operations, as there are no paved roads connecting the village to the outside world. It is registered with Brazil's civil aviation authority (ANAC) and operates under basic infrastructure conditions suited to small propeller-driven aircraft.
