Santarém – Maestro Wilson Fonseca International Airport (IATA: STM, ICAO: SBSN) serves the city of Santarém in the state of Pará, Brazil. It is the principal air gateway to the western Amazon region of Pará, linking the city to major Brazilian hubs and supporting both passenger and cargo operations. The airport was named in honor of Maestro Wilson Fonseca, a celebrated Santarém-born musician and composer. It handles a moderate volume of domestic traffic, with connections primarily to Belém, Manaus, and other regional cities, and has international designation though scheduled international services have been limited. The facility is operated under the Brazilian airport authority structure and plays a vital role in regional connectivity given the limited road infrastructure in the Amazon basin, making air travel essential for much of the population.
