Si Rat Malai (Thai: สี่รัฐมาลัย, lit.'Four Malay States') is a former administrative division of Thailand. It included the four northern states of Kedah, Perlis, Kelantan, and Terengganu in British Malaya annexed by the Axis-aligned Thai government after the Japanese invasion of Malaya.

The Thai authorities made Alor Setar the centre for the administration of the territory. Thailand administered the states as Syburi (ไทรบุรี), Palit (ปะลิส), Kalantan (กลันตัน) and Trangkanu (ตรังกานู) provinces from 18 October 1943 until the surrender of the Japanese at the end of the war.
