National Archives of Thailand

The National Archives of Thailand (NAT) (Thai: สำนักหอจดหมายเหตุแห่งชาติ; RTGS: samnak ho chot mai het haeng chat ) is a Thai government agency under the Fine Arts Department of the Ministry of Culture.

Records of value donated by individuals interested in their preservation are retained as archival collections.

According to Thai culture researcher Phuthorn Bhumadhon, when he wants to search the history of the Ayutthaya period, he has to go to archives in France.
