Saharat Thai Doem (Thai: สหรัฐไทยเดิม, lit. 'Unified Former Thai Territories') was an administrative division of Thailand. It encompassed parts of the Shan States of British Burma annexed by the Thai government after the Japanese conquest of Burma.

By means of this annexation, Axis-aligned Thailand expanded northwards to the 22nd parallel north and gained a border with China. Chiang Tung (Kengtung) was the administrative headquarters of the province.^[1] After the Phibun government fell in August 1944, the new Thai government communicated to the British that it renounced all claims to the Shan States and northern Malaya, and that it would immediately return the territories to Britain. The Churchill government did not accept the Thai overture, and was prepared to retaliate.^[2] The Thai army evacuated in August 1945.^[3]
