Nam Sang Wai is a wetland area to the north of Yuen Long, in Hong Kong. Nam Sang Wai covers a roughly triangular area. It is bordered by the Shan Pui River in the west, separating it from Yuen Long Industrial Estate, the Kam Tin River in the east and a branch of the Kam Tin River in the south. In what is considered to be a landmark case in the history of Hong Kong's planning law regime, the Privy Council upheld the decision of the Town Planning Appeal Board approving development of a large scale residential, golf course, and nature reserve at Nam Sang Wai .

南生圍位於香港元朗橫洲東面，被錦田河及山貝河包圍。兩河之間的交匯處有一小島，猶如一個雀鳥天堂。南生圍的美景不僅吸引雀鳥，近年不少市民，特別是攝影愛好者，皆會趁假日到來觀鳥拍照。一大片的山林美景、蜿蜒河流及長木橋等等亦成為拍攝婚紗照的理想背景。
