Sisudachan^[1][2] (Thai: ศรีสุดาจันทร์; early 1500s – 1548 in Ayutthaya) was a queen of Ayutthaya by marriage to King Chairacha of Ayutthaya. At his death, between 1546 and 1548, she served as regent for her son Yot Fa.

According to the chronicles of that time, she was responsible for the assassination of both sovereigns. Accomplice of the second regicide was her lover Phan But Sri Thep, which Sisudachan had him appointed first co-regent and then King with the title Khun Worawongsathirat. Opposed by a good part of the court, they were victims of an ambush by the nobles of the Sukhothai clans and were executed just weeks after Worawongsathirat had ascended the throne.^[3]
