Tungussko-Chunsky district was located in the south-east of the Evenk Autonomous Okrug. The total area of the district was 111,600km2 - the district's length from west to east at the widest point was 340 kilometres, and from north to south was 540 kilometres.
When the district was created, the administrative centre was the village of Strelka-Chunya. However, in 1935, the administrative centre was changed to the village of Vanavara. The reason for the change was the distance of Strelka-Chunya from the district's main waterway, Podkammenoy Tunguski, which caused difficulties in communication with other settlements in the district.
The district contained 5 settlements (postal codes in parentheses):
The village of Vanavara (648490) - population 2,943[3]
The village of Mutoray (648483) - population 90[4]
