Bulgan Province () is one of the 21 provinces of Mongolia, located in the north of the country, bordering Russia. Its capital is also named Bulgan.
Bulgan Province was officially established on 15 January 1938 following 1937 decision by the Council of Ministers of the Mongolian People's Republic, being separated from Selenge Province.
In 1994, Orkhon Province was taken out from Bulgan Province area to form an independent province.
The province (or aimag) is surrounded by Russia (Buryatia) to the north, the Khövsgöl Province to the northwest, Arkhangai to the southwest, ÃÂvörkhangai to the south, Töv to the southeast, and Selenge to the northeast. The small Orkhon Province forms an enclave at the border with Selenge.
The north of the aimag is characterized by alpine forests, gradually blending into the arid steppe plains of the central Mongolian highland. The main rivers are the Orkhon and the Selenge, the first of which enters the aimag from ÃÂvörkhangai, while the second enters from Khövsgöl Province. As a result, southern and central Bulgan is one of Mongolia's few arable regions.
The province is divided into 16 sums (districts) and 75 bags (subdistricts).
