Syburi (Thai: ไทรบุรี;rtgs: Sai Buri, meaning "City of the Banyan") is the name for the Malay state of Kedah returned to Thailand when the Japanese occupied British Malaya during World War II.

General Plaek Phibunsongkhram signed a secret agreement with the Japanese Empire on 14 December 1941 and committed the Thai armed forces to participate in the planned Malayan Campaign and Burma Campaign. An alliance between Thailand and Japan was formally signed on 21 December 1941. On 25 January 1942, the Thai government, believing the Allies beaten, declared war on the United States and the United Kingdom. As a reward for entering into a military alliance with the Japanese, the latter agreed to return to Thailand the four Malayan provinces ceded to the British in 1909, Kedah, Perlis, Kelantan, and Terengganu, as well as parts of Shan State in British Burma. In July 1943, Japanese Prime Minister Hideki Tojo announced that Kedah (along with Perlis, Kelantan and Terengganu) were to be returned to Thailand as part of the military alliance signed between Thailand and Japan on 21 December 1941.
