Chao Phraya chou pry [key], Mae Nam Chao Phraya, or Menam Chao Phrayaboth: m?nm [key], chief river of Thailand, c.140 mi (230 km) long, formed by the confluence of the Ping (c.300 mi/480 km long) and the Nan (c.500 mi/800 km) rivers at Nakhon Sawan, W central Thailand. It flows S past Bangkok to the Gulf of Thailand and is navigable for its entire length.

The many distributaries of the Chao Phraya delta are interconnected by canals that serve both for irrigation and for transportation.
