The Palace Law of Succession, Buddhist Era 2467 (1924) (Thai: กฎมณเฑียรบาลว่าด้วยการสืบราชสันตติวงศ์ พระพุทธศักราช ๒๔๖๗; rtgs: Kot Monthian Ban Wa Duai Kan Suep Ratchasantatiwong Phra Phutthasakkarat Song Phan Si Roi Hok Sip Chet) governs succession to the Throne of the Kingdom of Thailand, under the ruling House of Chakri. Succession matters prior to the end of absolute monarchy in 1932 could be contentious, especially during the Ayutthaya period from the 14th to 18th centuries. In 1924, King Vajiravudh (Rama VI) attempted to clarify the succession process by laying down the Palace Law of Succession. It was promulgated and came into effect in November 1924 as, in part, an attempt to eliminate the vagueness relating to succession within the Thai monarchical regime and to systematically resolve previous controversies. In 1932, after Siam became a constitutional monarchy, various amendments relating to succession were introduced. The 1997 Constitution of Thailand relied on the law with regards to succession, but the 2006 Interim Constitution made no mention of succession, leaving it to "constitutional practice." The 2007 Constitution again relied on the Palace Law. The preamble of the 2014 interim constitution of Thailand abrogated the 2007 Constitution, with the exception of chapter 2, concerning the monarchy and the succession.

The original Palace Law of A.D. 1360 relating to succession since Ayutthaya Kingdom period (1351–1767) did not lay out a clear system for determining a successor upon the death of a king. Rather, it provided a frame of reference from which the next king could be chosen. Typically, the new king would be either the late king's son born of a major queen or consort (Thai: หน่อพระพุทธเจ้า; rtgs: no phra phuttha chao), or one of his brothers. The Law also provided rules by which someone who was neither a son nor a brother of the deceased king could accede to the throne, should the situation or circumstances require it.
