Fazenda Fortaleza do Inajá is a small private airstrip located in the municipality of Santa Maria das Barreiras, in the southern portion of the state of Pará, Brazil. It serves as a general aviation facility associated with agricultural farmland operations typical of the region. The airstrip is identified by the ICAO code SJM2 and has no assigned IATA code, indicating it does not handle scheduled commercial passenger services. Like many fazenda airstrips in Brazil's interior, it primarily supports light aircraft used for farm management, cargo, and private transport in a region with limited road infrastructure.
