Kuala Lumpur, officially the Federal Territory of Kuala Lumpur (Malay: Wilayah Persekutuan Kuala Lumpur) and colloquially referred to as KL, is a federal territory and the ceremonial, legislative and judicial capital city of Malaysia. It is one of the fastest growing cities in Asia and the largest city in Malaysia, covering an area of 243 km2 (94 sq mi) with a census population of 1,982,112 as of 2020.

The geography of Kuala Lumpur is characterised by the huge Klang Valley, bordered by the Titiwangsa Mountains in the east, several minor ranges in the north and the south, and the Strait of Malacca in the west. Kuala Lumpur is a Malay term that translates to "muddy confluence" and is located at the confluence of the Klang and Gombak rivers.

Kuala Lumpur was originally a small hamlet of just a few houses and shops at the confluence of the Sungai Gombak and Sungai Klang (Klang River). Kuala Lumpur became established as a town circa 1857, when the Malay Chief of Klang, Raja Abdullah bin Raja Jaafar, aided by his brother Raja Juma'at of Lukut, raised funds from Malaccan Chinese businessmen to hire Chinese miners from Lukut to open new tin mines there. The miners landed at Kuala Lumpur and continued on foot to Ampang, where they opened the first mine. Kuala Lumpur was the furthest point up the Klang River to which supplies could conveniently be brought by boat, and therefore became a collection and dispersal point serving the tin mines.

Kuala Lumpur achieved city status on 1 February 1972, becoming the first settlement in Malaysia to be granted the status after independence. Later, on 1 February 1974, Kuala Lumpur became a federal territory. The territory of Kuala Lumpur expanded to 96 square miles by absorbing the surrounding areas. Kuala Lumpur ceded from Selangor to be directly controlled by the central government, and it ceased to be capital of Selangor in 1978 after the city of Shah Alam was declared the new state capital.
