The fall of Angkor, also known as the sack of Angkor or siege of Angkor, refers to the capture and looting of the Khmer capital at Angkor by the Ayutthaya Kingdom, conventionally dated to 1431. Thai chronicle traditions describe a siege of Angkor Thom lasting around seven months, beginning in 1430 and ending with the city's capture in 1431.

In the aftermath, the Khmer court shifted its political centre southwards, with Ponhea Yat associated in later accounts with moves to Basan (Srey Santhor) and then to Chaktomuk (present-day Phnom Penh), a transition often used to mark the start of the Post-Angkor period. While Angkor ceased to function as the kingdom's main political capital, archaeological and inscriptional evidence indicates that major Angkorian temple sites continued to see occupation and religious use after the 15th century.
