Kapuas Hulu Regency is a regency in West Kalimantan province of Indonesia. Located around the upper drainage area of the Kapuas River, it has a total land area of 31,318.25 square kilometres or around 21.3% of West Kalimantan province's area. The regency seat is located in town of Putussibau, where most of its economic and government activities take place. Kapuas Hulu Regency is one of the few Indonesian regencies having a land border with another country (in this case, with Malaysia). It is also the largest regency in the province by land area. Due to its relatively large area, it is sparsely populated compared to neighbouring regencies around it. The regency had a population of 222,160 at the 2010 Census and 252,609 according to the 2020 Census; the official estimate as at mid 2023 was 262,404 (comprising 134,520 males and 127,890 females).

The area was under kingdom of Selimbau, which was under influence of Sultanate of Sambas in early 17th and 18th century. Other than it, there were several smaller kingdoms and Malay chieftains such as Suhai, Jongkong, and Bunut, scattered around the region.

On 1823, Dutch settlers began exploring the region and Dutch colonial government signed a treaty with kingdom of Selimbau, acknowledging its domination over smaller kingdoms and chieftains in the region. Over time, the kingdom gradually lost its autonomy and the last king of Selimbau, Haji Gusti Usman, abdicated on 1925. The region was incorporated into Dutch East Indies and administrated from Sintang.

During Japanese occupation of Dutch East Indies, the region was administrated by Imperial Japanese Navy from Banjarmasin. Japanese opened a coal mine around Mentabah and Tebaung river in 1942 to support their war effort on Pacific. The locals welcomed Japanese at first, thought them to be liberator from Dutch rule. However, due to exploitation and treatment on locals, they turned against the Japanese later on. It was estimated around 1,000 native worked as Rōmusha died in the region during Japanese occupation. The occupation resulted in Majang Desa War or more popularly known as Dayak Desa War, with Japanese expelled from Borneo interior as the result. One of leader's war and Dayak chieftain, nicknamed Pang Suma, today is regarded as hero not only in the region but also Indonesia in general. The region became an autonomous royal region within West Kalimantan in 1946 and later became a regency under Law Number 3 of 1953.

There has been ongoing discussion about forming a new province, Kapuas Raya, which would include Kapuas Hulu as part of it, to be separated from West Kalimantan. However, due to a moratorium on new administrative division creations for financial reason since 2014, its creation has been put on halt by the Indonesian government.

The regency borders Sarawak in the north, Sintang Regency in the west and south, and East Kalimantan as well as Central Kalimantan in the east. Soil formation in the region is considered to be one of the oldest in Indonesian archipelago. There are numerous lakes, swamps, and wetlands in the region and lower region is often submerged by water from nearby rivers as long as six months a year. Settlements are mostly located around rivers due to historical importance of inland waterways in the past. There are 925,134 hectares of national park, 834.140 hectares of protected forest, and 769,000 hectares of production forest.

The regency has tropical climate with temperature between 22.9 and 33.5 Celsius, with 84.6% air humidity, and 38% sunlight intensity. The wettest month is May with average rainfall of 547.66 mm, and the driest is August with average 222.2 mm.

At the time of the 2010 Census, the regency was divided into 25 administrative districts (kecamatan). However this has since been reduced to 23 by the amalgamation of the former Danau Sentarum District into Selimbau District, and the amalgamation of the former Hulu Kapuas District into Putussibau Selatan District. The regency seat, Putussibau, consists of the urban parts of two districts, which are North Putussibau and South Putussibau; both form the first and second most populous districts in the regency. Due to regency seat not having clear official boundaries, the estimated population of the town could be as high as 50,000 people depending on where the speculative border is drawn; but both districts include extensive rural regions. Below is a list of the districts with their areas and their populations according the 2010 and 2020 Censuses, as well as the official estimates as at mid 2023. The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 278 rural desa and 4 urban kelurahan), and its post code.
