Iceland's Capital Region (Höfuðborgarsvæðið) is a region in southwestern Iceland covering 1,046 square kilometres. It consists of the national capital Reykjavík and six surrounding municipalities: Kópavogur, Hafnarfjörður, Garðabær, Mosfellsbær, Seltjarnarnes, and Kjósarhreppur.
As of 2025, 249,054 people live in the Capital Region, which is about two-thirds of Iceland's total population. Of those, 126,527 are male, 122,378 are female, and 149 identify as non-binary or other.
Reykjavík is the most populated municipality with 138,772 residents as of 2025. Kjósarhreppur is the largest by land area at 284 square kilometres, but it is entirely rural with only 301 inhabitants.
The Capital Region is one of two NUTS-2 statistical regions of Iceland under the European Union's Nomenclature of Territorial Units for Statistics. Iceland's individual regions, including the Capital Region, serve as NUTS-3 units within that broader classification.
More than 98% of the Capital Region's population lives in the Greater Reykjavík urban area, which recorded 244,177 residents as of 2024. The remaining population is spread across the minor urban areas of Álftanes, Grundarhverfi, and Mosfellsdalur, with a small fraction classified as rural.
The Capital Region has a very high Human Development Index and is described as one of the most developed regions in Europe. Nearly 25% of its labour force works in professional and administrative roles, including government offices.
