It covers an area of 13,181.92&nbsp;km<sup>2</sup> and had a population of 112,663 at the 2010 Census<ref name="Biro Pusat Statistik 2011">Biro Pusat Statistik, Jakarta, 2011.</ref> and 151,844 at the 2020 Census;<ref name="Badan Pusat Statistik 2021">Badan Pusat Statistik, Jakarta, 2021.</ref> the official estimate as at mid 2025 was 173,688.<ref name="Badan Pusat Statistik 2026">Badan Pusat Statistik, Jakarta, 27 February 2026, ''Kabupaten Bulungan Dalam Angka 2026'' (Katalog-BPS 1102001.6501)</ref> The administrative centre is at Tanjung Selor.

==History== The modern iteration of Bulongan Regency (the original spelling) was established on 26 June 1959, replacing the earlier Special Region of Bulongan which was governed by the Sultanate of Bulungan (the last sultan: Maulana Muhammad Djalaluddin or Datuk Tiras). It was then one of the founder regencies of East Kalimantan during its establishment in 1956.<ref>{{cite web|url=https://peraturan.bpk.go.id/Details/51518/uu-no-27-tahun-1959|title=UU No. 27 Tahun 1959|website=peraturan.bpk.go.id|access-date=2025-07-26}}</ref> It is unknown when exactly this regency changed its spelling into the current one.

Bulungan was originally co-extensive with what subsequently became the province of North Kalimantan. On 8 October 1997 the town of Tarakan was cut out of the regency to become an independent city. Two years later, on 4 October 1999, the remaining territory of the regency was split to create two additional regencies - Malinau Regency and Nunukan Regency. On 17 July 2007, three more districts (''kecamatan'') was split from Bulungan Regency to form a new regency, Tana Tidung Regency.<ref>{{cite web |title=UU No. 34 Tahun 2007 tentang Pembentukan Kabupaten Tana Tidung Di Provinsi Kalimantan Timur |url=https://peraturan.bpk.go.id/Home/Details/39947#:~:text=UU%20No.%2034%20Tahun%202007,Kalimantan%20Timur%20%5BJDIH%20BPK%20RI%5D |website=peraturan.bpk.go.id |publisher=Audit Board of Indonesia |access-date=31 January 2022 |date=2007 |language=id}}</ref>

Bulangan Regency had originally been part of the East Kalimantan province, but in 2012 it - together with the areas carved out of it in 1997, 1999 and 2007 - became part of the newly created North Kalimantan province. Tanjung Selor in Bulungan Regency was designated as the province's capital.<ref name=":3">{{Cite web|title=Sejarah {{!}} Kalimantan Utara|url=https://kaltaraprov.go.id/profil/sejarah|access-date=31 May 2021|website=kaltaraprov.go.id}}</ref>
