Pedra Preta Airport (ICAO: SJMK) is a small general aviation airstrip located near the municipality of Uiramutã in the state of Roraima, Brazil. It serves a remote area in the extreme north of the country, close to the borders with Venezuela and Guyana, within or near the Raposa Serra do Sol indigenous territory. The airport primarily supports small aircraft operations, providing essential air access to an otherwise isolated region where road infrastructure is extremely limited. It does not handle scheduled commercial airline service and has no IATA code assigned. Given its remote location and limited infrastructure, the airstrip plays a logistical role for local communities, government operations, and occasional humanitarian or supply missions in this frontier region of Amazonia.
