Cape Town (Afrikaans: Kaapstad, [ˈkɑːpstat]; Xhosa: iKapa, [íkáːpa]), also known as the Mother City, is South Africa's oldest city. It serves as the country's legislative capital, being the seat of the South African Parliament. It is the country's second-largest city (after Johannesburg) and the largest in the Western Cape. The city is part of the City of Cape Town metropolitan municipality.

The city is known for its harbour, its natural setting in the Cape Floristic Region, and for landmarks such as Table Mountain and Cape Point. In 2014, Cape Town was named the best place in the world to visit by The New York Times and similarly by The Daily Telegraph in 2016.

Located on the shore of Table Bay, the City Bowl area of Cape Town is the oldest urban area in the Western Cape, with a significant cultural heritage. It was founded by the Dutch East India Company (VOC) as a supply station for Dutch ships sailing to East Africa, India, and the Far East. Jan van Riebeeck's arrival on 6 April 1652 established the VOC Cape Colony, the first permanent European settlement in South Africa. Cape Town outgrew its original purpose as the first European outpost at the Castle of Good Hope, becoming the economic and cultural hub of the Cape Colony. Until the Witwatersrand Gold Rush and the development of Johannesburg, Cape Town was the largest city in southern Africa.

The city has a long coastline on the Atlantic Ocean, which includes False Bay, and extends to the Hottentots Holland mountains to the east. The Table Mountain National Park is within the city boundaries and there are several other nature reserves and marine-protected areas within, and adjacent to, the city, protecting the diverse terrestrial and marine natural environment.
