Phrabat Somdet Phra Borommaracha Thirat IV (Thai: พระบาทสมเด็จพระบรมราชาธิราชที่ 4) or Phrabat Somdet Phra Borommarachathirat No Phutthangkun (Thai: พระบาทสมเด็จพระบรมราชาหน่อพุทธางกูร) , formerly Prince Athittayawong, was the short-reigning king of Ayutthaya from 1529 to 1533. Prince Athittayawong was the son of Ramathibodi II and became the Upparat in 1515. Following his father's death, Athittayawong succeeded the Ayutthayan throne as Borommaracha IV. He appointed his brother, Prince Chairachathirat, as the Upparat at Phitsanulok. Borommaracha IV died abruptly in 1533 due to an epidemic, leaving the throne to his five-year-old son, Prince Ratsadathirat.
