Overview

Koshi Province occupies the eastern seventh of Nepal, from the Indian border on the Terai to the Tibetan frontier on the high Himalaya. Its provincial assembly adopted the name 'Koshi' in 2023, after the great Saptakoshi river system that drains it; until then it was known simply as Province No. 1.

With its capital at Biratnagar — long one of Nepal's principal industrial cities — the province blends a productive plains economy with the tea estates of Ilam, the trekking gateways of the Khumbu, and some of the country's most significant hydropower sites on the Koshi tributaries.

Geography

Easternmost province, stretching from the Terai plains of Jhapa and Morang up to the world's highest peaks in Solukhumbu and Taplejung — it contains Mt Everest (Sagarmatha) and Kanchenjunga, the world's first and third highest mountains.

Economy

Sources & data note

Population, density and share figures are the final published counts of the National Population and Housing Census 2021 (National Statistics Office). Each province's total area is summed from the official statistical areas of its districts, so it stays consistent with the district dataset on this site. Provincial capitals are the permanent headquarters fixed by each provincial assembly. The 2015 constitution created seven provinces, initially numbered; each was later given a name by its assembly (Province No. 1 → Koshi in 2023 being the last).
