East Kalimantan
province of Indonesia
East Kalimantan (Indonesian: , abbreviated as Kaltim) is a province of Indonesia. Its territory comprises the eastern portion of Borneo/Kalimantan. It had a population of about 3.03 million at the 2010 census (within the present boundary), and 3.766 million at the 2020 census; the official estimate in mid-2025 was 4,267,600. Its capital is Samarinda, the most populous city on the entire island of Borneo.
East Kalimantan has a total area of 127,346.92 square kilometres (49,168.92 sq mi) and is the third least densely populated province in Kalimantan (after North Kalimantan and Central Kalimantan). The majority of the region shares a maritime border to the east with West Sulawesi and Central Sulawesi; its Cape Mangkalihat separates the Makassar Strait from the Celebes Sea. Its former northernmost region was split off on 25 October 2012 and is now the separate province of North Kalimantan; meanwhile it still shares land border to the west with West Kalimantan and Central Kalimantan; to its south, East Kalimantan borders South Kalimantan. The province bordered Sabah, Malaysia before the creation of North Kalimantan, and still has a short border with Sarawak, Malaysia through Mahakam Ulu Regency.
Since 11 January 2013, East Kalimantan has been divided into seven regencies and three cities. The proposed capital city of Indonesia, Nusantara, is currently constructed entirely within the province.

Why this record matters
“East Kalimantan” is worth following because a concise public description often conceals a longer documentary argument. Here, East, Kalimantan and province provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q3899. VIAF identifies the subject as 144236486. The Library of Congress control number is n79108863. Authority coordinates are 1.050, 116.317. 4 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2010, 2020, 2025 and 2012.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
