Fazenda Cocal Airport is a small private airstrip located near Santa Maria das Barreiras, a municipality in the far south of Pará state, Brazil. It serves the agricultural and ranching activities typical of the region, providing light aircraft access to a remote area with limited road infrastructure. The airstrip operates under the ICAO code SIT4 and has no assigned IATA code, reflecting its status as a private or restricted-use facility rather than a commercial public airport. It is characteristic of the many fazenda (farm or ranch) airstrips found throughout Brazil's interior, which are essential for connecting remote landholdings to larger urban centers.
