Bombay Reef (Chinese: 浪花礁; pinyin: Lànghuājiāo, Vietnamese: đá Bông Bay) is an atoll of the Paracel Islands.

[3] In the early hours of 20 December 1946, en route from Hong Kong to Singapore for decommissioning, HMS Aire ran aground on Bombay Reef.

In early May 1967 the 87-foot (27 m)[6] steel sailing schooner Dante Deo, with six men and a six-year-old boy on board,[7] was wrecked on Bombay Reef.

In the aftermath of the First Indochina War until 1974 Vietnam occupied Pattle Island, approximately 60 nautical miles (110 km) away.

Bombay Reef is administered and governed by the People's Republic of China and patrolled by the Chinese border police.
