Hong Kong, officially the Hong Kong Special Administrative Region of the People's Republic of China (HKSAR), is a metropolitan area and special administrative region of the People's Republic of China on the eastern Pearl River Delta of the South China Sea. With over 7.5 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated places in the world.

The name of the territory, first romanised as "He-Ong-Kong" in 1780, originally referred to a small inlet located between Aberdeen Island and the southern coast of Hong Kong Island. Aberdeen was an initial point of contact between British sailors and local fishermen. Although the source of the romanised name is unknown, it is generally believed to be an early phonetic rendering of the Cantonese pronunciation 'hēung góng'. The name translates as "fragrant harbour" or "incense harbour". "Fragrant" may refer to the sweet taste of the harbour's freshwater influx from the Pearl River or to the odour from incense factories lining the coast of northern Kowloon.
