Tang Lung Chau Lighthouse, Coastal lighthouse in Tsuen Wan District, Hong Kong.

Tang Lung Chau Lighthouse is an 11.8-metre steel skeletal tower with a white top, standing on Tang Lung Chau island in the Kap Shui Mun channel. Its lighting apparatus and steel framework were both made in Britain. Beside the tower is a brick building that housed the lighthouse keepers, with bedrooms, a kitchen, a toilet and a storeroom.

Tang Lung Chau Lighthouse was commissioned on 29 April 1912 and was operated manually, with a keeper stationed on the island. It was converted to automatic operation around the 1980s and is now managed by the Marine Department. On 29 December 2000 the Antiquities and Monuments Office declared it a monument, together with Waglan Lighthouse.

The lighthouse is also called Kap Sing Lighthouse (汲星燈塔), after Kap Shui Mun, the channel it marks. It was listed as a declared monument on 29 December 2000, together with Waglan Lighthouse, and is now managed by the Marine Department.

The lighthouse stands on Tang Lung Chau, a small island in the Kap Shui Mun channel off Tsuen Wan; there is no regular ferry, so visitors arrive by chartered boat. The tower and the adjoining brick keeper's house sit close together on the island, and the site is managed by the Marine Department, so landing and access depend on sea and tidal conditions.

The keeper's brick house beside the tower held a bedroom, kitchen, toilet and storeroom, and its drinking water came from rain collected on the roof and led into an underground tank. The lighthouse was automated in the 1980s, so no keeper lives there now.
