索罟群岛是香港的一组群岛，位于新界大屿山离岛区西南部水口半岛对出海域，为香港境内最西南区域，邻近由广东省珠海市香洲区桂山镇管辖的桂山岛。

索罟群岛主要由以下岛屿及礁石群所组成：

• 大鸦洲、圆岗洲
• 小鸦洲、湾口洲
• 樟木头、高排、龙船排
• 孖洲、圆洲、石洲
• 头颅洲

The Soko Islands (Chinese:索罟群島) are a group of islands in Hong Kong. The group consists of Tai A Chau, Siu A Chau and several smaller nearby islands, in the southwestermost waters of the territory, to the southwest of Lantau Island.

Now largely uninhabited, the islands formerly accommodated a refugee camp for Vietnamese boat people. CLP Power is currently proposing them as the site for a terminal to receive liquefied natural gas (LNG) for use in electricity generation. This proposal is opposed by local environmental groups because the surrounding waters are an important habitat for various marine species, particularly the rare Chinese White Dolphin.
