Tsing Yi (Chinese: 青衣), or Tsing Yi Island (Chinese: 青衣島) is an island in the urban area of Hong Kong, to the northwest of Hong Kong Island and south of Tsuen Wan. With an area of 10.69 km², the island has extended drastically by reclamation along almost all its natural shore and the annexation of Nga Ying Chau and Chau Tsai. Three major bays or harbours, Tsing Yi Lagoon, Mun Tsai Tong and Tsing Yi Bay in the northeast, have been completely reclaimed for new towns.

The island can be divided as four quarters, the northeast quarter is a residential area, the southeast quarter is Tsing Yi Town, the southwest holds heavy industry, and the northwest includes a recreation trail, a transportation interchange and some dockyards and ship building industry. The island is at the northwest part of Victoria Harbour and part of its development is under the Law of Hong Kong, Chapter 531, the Protection of the Harbour Ordinance.

Tsing Yi (青衣) iterally means "green (or blue) clothes", but is also a kind of fish, probably blackspot tuskfish, once abundant in nearby waters. People named the island after the fish. Tsing Yi Tam (青衣潭, lit. Tsing Yi Pool) or Tsing Yi Tam Shan (青衣潭山, lit. Tsing Yi Pool Hill) also appeared on some early Chinese maps.
