'''Central Thailand''' (Central Plain) (historically also known as '''Siam''' or '''[[Dvaravati]]''') is one of the [[regions of Thailand]], covering the broad [[alluvial plain]] of the [[Chao Phraya River]]. It is separated from northeast Thailand ([[Isan]]) by the [[Phetchabun Mountains|Phetchabun mountain range]]. The [[Tenasserim Hills]] separate it from [[Myanmar]] to the west. In the north it is bounded by the [[Phi Pan Nam Range]], one of the hilly systems of [[northern Thailand]]. The area was the heartland of the [[Ayutthaya Kingdom]] (at times referred to as [[Siam]]) and is still the dominant area of [[Thailand]] since it contains the world's most [[primate city#Examples|primate city]], [[Bangkok]].
