This is a list of rivers of Thailand. The rivers are arranged alphabetically within their respective provinces or special governed districts. The same river may be found in more than one province as many rivers cross province borders.
The Mekong, Salween, and Golok are border rivers. The Mekong forms part of Thailand's border with Laos, the Salween with Myanmar, and the Golok with Malaysia. The Thai word for river is "mae nam", which literally means "mother water."
