Dallas Reef (7°38′N 113°48′E / 7.633°N 113.800°E / 7.633; 113.800), also known as Guangxing Jiao and Nan Chiao (Chinese: 光星礁) in China, Terumbu Laya in Malaysia, đá Suối Cát in Vietnam and Rajah Matanda in the Philippines, lies on the SW extremity of Dangerous Ground (South China Sea) in the Spratly Islands of the South China Sea.[1]

It is approximately 7km long and 2km wide, and encloses a lagoon ~15m deep. It is 9km west of Ardasier Reef, and 26km north of Swallow Reef.

As with all of the Spratly Islands, the ownership of the atoll is disputed. It is controlled by Malaysia, and claimed by the People's Republic of China, the Republic of China (Taiwan) and Vietnam.[2]
