流浮山（英语：Lau Fau Shan）位于香港元朗区西部，靠近后海湾。

流浮山原址位于天水围以西，厦村以北的一座小山丘。但后来主要代表其西面数条乡村较旺盛的地方。

流浮山以其出产的海鲜闻名，尤其是蚝。因为该处位于后海湾畔，临近珠江口，有淡水流入，所以适合养蚝。只可惜70年代流浮山屡受**武装炮艇侵扰及掳人，加上珠江三角洲水质污染日趋严重，乡村人口递减和天水围市区不断发展，流浮山的渔业，尤其是蚝产量已大不如前，及至80年代蚝业始起死回生。然而该处仍有不少海鲜酒家，每逢假日均有不少旅行团专程前往品尝。

Lau Fau Shan (Chinese:流浮山; literally: "Floating mountain") is an area in the New Territories of Hong Kong. It is at the shore of Deep Bay, near Tin Shui Wai and facing Shekou in Shenzhen, China. It is traditionally famous for fresh oysters. About 100 tons were harvested every year, some for consumption in Hong Kong restaurants and some for export to neighboring countries. However, little remains of this today since most of the inhabitants of Lau Fau Shan have given up oyster culture.
