Windhoek ( /ˈvɪnt.hʊk/ VINT-huuk; German:  Windhuk (help·info)) is the capital and largest city of the Republic of Namibia. It is located in central Namibia in the Khomas Highland plateau area, at around 1,700 metres (5,600 ft) above sea level. The population of Windhoek in 2011 was 322,500 and grows continually due to an influx from all over Namibia.

The town developed at the site of a permanent spring known to the indigenous pastoral communities. It developed rapidly after Jonker Afrikaner, Captain of the Orlam settled here in 1840 and built a stone church for his community. However, in the decades thereafter multiple wars and hostilities led to the neglect and destruction of the new settlement such that Windhoek was founded a second time in 1890 by Imperial German army Major Curt von François.

Windhoek is the social, economic, and cultural centre of the country. Nearly every Namibian national enterprise, governmental body, educational and cultural institution is headquartered here.

The City of Windhoek is traditionally known by two names: ǀAiǁGams, (Khoekhoe: hot springs) and Otjomuise (Otjiherero: place of steam). Both traditional names reference the hot springs near today's city centre.
