Tsuen Wan New Town is a new town in Hong Kong. It spans Tsuen Wan, Kwai Chung and the eastern part of Tsing Yi Island. Traditionally, the administrative officials of Tsuen Wan managed the area of Tsuen Wan proper, Kwai Chung, Tsing Yi Island, Ma Wan and Northeast Lantau Island. Its total development area is about 24 square kilometres (9.3 sq mi). The population of the new town is approximately 801,800, with the planned capacity being 845,000.

The Hong Kong government started developing new towns in the 1950s to accommodate Hong Kong's booming population. During the first phase of development, the newly developed towns were called "satellite towns", a concept borrowed from the United Kingdom, of which Hong Kong was a colony. Kwun Tong, located in eastern Kowloon, and Tsuen Wan, located in the south-west of the New Territories, were designated as the first satellite towns, when the urban area in Hong Kong was still relatively small, restricted to the central and western parts of Kowloon Peninsula and the northern side of Hong Kong Island. Wah Fu Estate was also built in a remote corner on the southern side of Hong Kong Island, with similar concepts but at a smaller scale.
