Pedra Branca Airport, designated with ICAO code SJMJ, is a small general aviation airstrip located near Uiramutã in the far northern reaches of Roraima state, Brazil. The municipality of Uiramutã sits close to the borders with Venezuela and Guyana, in a region dominated by the Raposa Serra do Sol indigenous territory. The airstrip serves primarily as a lifeline for local communities, supporting light aircraft operations for cargo, medical flights, and occasional government or missionary access. There is no scheduled commercial airline service at this facility. Given the extreme remoteness of the area and the lack of paved road infrastructure, small aircraft represent one of the most reliable means of accessing Uiramutã and surrounding indigenous communities.
