Tai Nam Wan (Chinese: 大南灣), or Nam Wan (南環, correctly 南灣), was a bay on the south coast of Tsing Yi Island, Hong Kong.
As there is another south bay, Nam Wan (南灣), near Sai Tso Wan to the west of the island, some people refer to this bigger one as big south bay.
The two characters for Wan in Cantonese are pronounced identically except for the tone.
The bay is south of Tsing Yi Peak, the highest point on the island, between Nam Wan Kok and Ng Tsang Lau and faces the west water of Victoria Harbour.
[1] The bay was completely reclaimed for Tsing Yi Power Station and the shore line straightened.
