Mutum Airport (ICAO: SJLX) is a small general aviation airstrip located near Uiramutã, a municipality in the far northeastern corner of the state of Roraima, Brazil. The area sits close to the borders with Venezuela and Guyana and is largely within or adjacent to the Raposa Serra do Sol indigenous territory. The airport serves primarily as a local access point for a region with very limited road infrastructure, supporting government operations, indigenous community access, and occasional light aircraft traffic. It is not served by scheduled commercial airline services. Given the remoteness of Uiramutã, the airstrip plays a logistical role for humanitarian, administrative, and supply missions into an otherwise difficult-to-reach frontier zone.
