Gulf of Thailand

The Gulf of Thailand, formerly the Gulf of Siam, is an inlet of the South China Sea.

Bordered by Thailand, Cambodia, and the southwestern edge of Vietnam, the gulf's maximum width is 350 miles (560 km), and it extends approximately 450 miles (725 km) in length.

The Gulf of Thailand is quite shallow along the coastal areas, and those waters provide lucrative fishing grounds. Many rivers flow into the Gulf of Thailand, with the Chao Phraya being the most significant.
