Prasat Thong (Thai: ปราสาททอง, pronounced [prāː.sàːt.tʰɔ̄ːŋ]; c. 1599–1655; r. 1629–1655) was the first king of the Prasat Thong dynasty, the fourth dynasty of the Siamese Ayutthaya Kingdom. Before being king, he defeated a rebellion led by the king's son Phra Sisin by working with Japanese mercenary Yamada Nagamasa. He gained power in 1629 by attacking the palace and placed a puppet king who he would later execute. Under his reign, he subjugated Cambodia but lost Siam's Northern principalities.
