Tsing Chau (Chinese: 青洲; pinyin: Qīngzhōu) or Pillar Island was an island in the Kwai Chung area of Hong Kong, sitting on the mouth of Gin Drinker's Bay, by the side of Rambler Channel, opposite to Tsing Yi Island.
In the 1960s, the bay was reclaimed and Tsing Chau became a land extension of Kwai Chung. The south of island is Kwai Chung Container Terminals. In the early 1970s, a cross-channel bridge, Tsing Yi Bridge, was built and the island is at the Kwai Chung end of the bridge. The north side of the island stands Kwai Chung Incineration Plant, which was closed and partly demolished in the early 1990s.
