Fazenda 3 Marias Airstrip (ICAO: SJH6) is a small private airstrip located in the municipality of Cocos, in the western region of Bahia state, Brazil. It serves the agricultural operations of the Fazenda 3 Marias farm estate, as is typical of privately owned airstrips in Brazil's interior agricultural regions. The airstrip is not served by commercial airlines and does not handle scheduled passenger traffic. It primarily supports general aviation, including light aircraft used for farm management, cargo transfers, and private transport in this remote region of the Brazilian cerrado.
