Pegunungan Bintang Regency or Bintang Mountains Regency ("Bintang" means "star") is a regency in the Indonesian province of Highland Papua. It was created on 11 December 2002 from the north-eastern districts of Jayawijaya Regency. It covers an area of 15,683 km², and had a population of 65,434 at the 2010 Census^[2] and 77,872 at the 2020 Census;^[3] the official estimate as at mid 2024 was 114,581 – comprising 61,112 males and 53,469 females.^[1] The administrative centre is the town of Oksibil.

Pegunungan Bintang is the Indonesian name for the Star Mountains, a mountain range that is also shared by Papua New Guinea. Similarly, Star Mountains Rural LLG in Western Province, Papua New Guinea is also named after the same mountain range.

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.^[4][5][6]

Astronomically, Pegunungan Bintang Regency is located between 3°04'00” – 5°20'00” South Latitude and 140°05'00” – 141°00'00” East Longitude. While geographically, Pegunungan Bintang Regency borders Keerom Regency and Jayapura Regency to the north, Boven Digoel Regency to the south, Yahukimo Regency to the west and Papua New Guinea to the east.^[7]
