Chinatown, Melbourne in the context of Swanston Street

Chinatown (Chinese: 唐人街) is a common term used to describe an ethnic enclave of Chinese people located outside of Mainland China, Hong Kong, Macau, and Taiwan, typically situated in an urban area. Chinatowns can be found around the world, including in Europe, Asia, Africa, Oceania, and the Americas. The history of Chinatowns date back to the Tang dynasty in the 10th century, arising from the nation's important role in global trade.

Binondo in Manila, established in 1594, is recognized as the world's oldest standing Chinatown. Notable early examples outside Asia include San Francisco's Chinatown in the United States and Melbourne's Chinatown in Australia, which were founded in the early 1850s during the California and Victoria gold rushes, respectively. A more modern example, in Montville, Connecticut, was caused by the displacement of Chinese workers in New York's Manhattan Chinatown following the September 11th attacks in 2001.

Chinese Australians (simplified Chinese: 华裔澳大利亚人; traditional Chinese: 華裔澳洲人; pinyin: Huáyì àodàlìyàrén or Huáyì àozhōurén) are Australians of Chinese origin. Chinese Australians are one of the largest groups within the global Chinese diaspora, and are the largest Asian Australian community. Per capita, Australia has more people of Chinese ancestry than any country outside Asia. As a whole, Australian residents identifying themselves as having Chinese ancestry made up 5.5% of Australia's population at the 2021 census.

The very early history of Chinese Australians involved significant immigration from villages of the Pearl River Delta in South China, with most such immigrants speaking dialects within the Yue dialect group. The Gold rushes lured many Chinese to the Australian colonies in the 19th century. As with many overseas Chinese groups the world over, early Chinese immigrants to Australia established several Chinatowns in major cities, such as Adelaide (Chinatown, Adelaide), Brisbane (Chinatown, Brisbane), Melbourne (Chinatown, Melbourne), Perth (Chinatown, Perth), and Sydney (Chinatown, Sydney). In the Australian external territory of Christmas Island, Australians of full or partial Chinese origin form the plurality of the population.
