Second Thomas Shoal, also known as Ayungin Shoal (Filipino: Buhanginan ng Ayungin, lit.'sandbank of silver perch'), Bãi Cỏ Mây (Vietnamese) and Rén'ài Jiāo (Chinese: 仁爱礁/仁愛礁), is a submerged reef in the Spratly Islands of the South China Sea, 105 nautical miles (194 km; 121 mi) west of Palawan, Philippines. It is a disputed territory and claimed by multiple nations.

The reef is occupied by a garrison of Philippine Navy personnel aboard a ship, the BRP Sierra Madre, that was intentionally grounded on the reef in 1999 and has been periodically replenished since then.
