Fazenda Mongaguá Airstrip (ICAO: SJ63) is a small private airstrip located near Cumaru do Norte, a municipality in the far south of Pará state, Brazil. It serves the operational needs of the Fazenda Mongaguá agricultural property, providing air access to an area with limited road infrastructure. The airstrip is typical of private farm strips found throughout Brazil's agricultural frontier regions, where light aircraft are essential for managing large landholdings and reaching remote areas. It is not open to the general public and does not support scheduled commercial aviation.
