Chinatown is an urban region containing a large population of Chinese people within a non-Chinese society.

The term Chinatown has also been used (mostly by non-Chinese) to describe urban areas where large numbers of people of Asian descent live and own small businesses, such as the Vietnamese, Japanese, Thais, and Koreans. Chinatowns are most common in Southeast Asia and North America, but growing Chinatowns can be found in Europe and Australia.
