Tsing Yi Bay (Chinese: 青衣灣) was a bay at the east side of Hong Kong's Tsing Yi Island, beside Rambler Channel, which is approximately Tsing Yi Park nowadays. The whole bay was reclaimed for the development of new town. Before reclamation, it was surrounded by places known as Tsing Leng Tsui (青嶺嘴), Sheung Ko Tan (上高灘), Ha Chung Mei (下涌尾), Tai Wong Ha (大王下) and Tsing Yi Town (青衣墟). The names of those places have since changed, and can now be translated, approximately, as Grand Horizon, Green Field Garden, Fung Shue Wo Road, Tsing Yi Estate and Tsing Yi Garden.
The mud and sand in the stream of Liu To settled on the shore of Tsing Yi Bay. A marsh was formed at the mouth of the stream. The bay became shollower and shollower. And finally, a neck, between Tsing Yi Town and Sheung Ko Tan, was formed. The inner water, now separate from the bay outside the neck, became Tsing Yi Lagoon.
In the 1980s the Hong Kong Government started to reclaim the bay in three phases. The bay has now been completely reclaimed and the shore has become straight, from Nga Ying Chau to Tsing Leng Tsui.
