Uraricoera Airport (ICAO: SJNC) is a small general aviation airstrip located near Alto Alegre in the state of Roraima, northern Brazil. It serves the remote communities along the Uraricoera River, a region characterized by dense Amazon rainforest and indigenous territories. The airport primarily supports light aircraft operations, missionary flights, and logistical access to areas that are otherwise difficult to reach by road. It plays an important role in connecting isolated communities with larger urban centers such as Boa Vista, the state capital of Roraima.
