Macclesfield Bank, also called Zhongsha Islands (Chinese: 中沙群島; pinyin: Zhōngshā Qúndǎo; literally "Central Sands Islands"), is an elongated sunken atoll of underwater reefs and shoals in the South China Sea. It lies east of the Paracel Islands, southwest of the Pratas Islands and north of the Spratly Islands. Its length exceeds 130 km (81 mi) southwest-northeast, with a maximal width of more than 70 km (43 mi). With an area of 6,448 km2 (2,490 sq mi) within the outer rim of the reef, although completely submerged without any emergent cays or islets, it is one of the largest atolls of the world.
The broken coral reef rim of Macclesfield Bank, with a width of up to 8 km (5 mi), has depths of 11.8 m (39 ft) at Pygmy Shoal on the northeast end of the bank and depths of 11.6 to 18 m (59 ft) elsewhere. Within the lagoon, Walker Shoal marks the least known depth of 9.2 metres. In general, the central lagoon is very deep, with depths up to 100 metres.

Territorial claims 
Some sources state that the Philippines claims this underwater feature. However, Jose Zaide, a Philippine diplomat of ambassadorial rank, has written that the Philippines does not claim the Macclesfield Bank.
As the bank is entirely underwater, some scholars have raised questions regarding the legality of territorial claims upon it with regards to the United Nations Convention on the Law of the Sea.
