Pegunungan Bintang Regency, located in Papua Pegunungan Province, Indonesia, has very distinctive geographical characteristics and is influenced by mountainous topography. This regency is part of the Maoke Mountains that stretch across the Papua region, so that most of its territory consists of mountainous areas with high peaks and deep valleys. This topography makes the Pegunungan Bintang area have rich biodiversity, thanks to the dense tropical forests that cover most of its territory. The tropical rainforests in this area not only function as ecosystem buffers but also as providers of natural resources. In addition, Pegunungan Bintang Regency has a number of rivers, especially the Digoel River and lakes, most of which flow south towards the Arafura Sea.The rivers in this area tend to have a fast flow due to the steep slopes of the mountains. The climate in this area is a tropical climate with relatively stable temperatures throughout the year and high rainfall, which supports the growth of lush vegetation. The mountainous and difficult-to-reach geographical conditions affect the transportation infrastructure in this regency, which is generally limited. Roads often become inaccessible during the rainy season, so air transportation is one of the main options for connecting this area to other regions. These overall geographical conditions influence various aspects of life in the Bintang Mountains, including the economy, infrastructure and way of life of the local people.

Astronomically, Pegunungan Bintang Regency is located between 3°04'00” – 5°20'00” South Latitude and 140°05'00” – 141°00'00” East Longitude.
