Ma Shi Chau

Ma Shi Chau (Chinese: 馬屎洲; Sidney Lau: Ma5Si2Jau1, literally "Horse Dung Island") is an island of Hong Kong, under the administration of Tai Po District.

It is located in Tolo Harbour in the northeast New Territories (near Sam Mun Tsai).

It is connected with another island, Yim Tin Tsai, by a tombolo traversable at low tide.
