Chế Chi, or Jaya Sinhavarman IV, was the king of Champa from 1307 - 1312. Because Chế Chi's Vietnamese mother refused to die with her husband and Chế Chi's father, Chế Mân, Chế Chi set out to recapture two districts ceded by Champa to Annam in their time of peace brought on by the wedding of his father and mother. He was defeated, however, and died a prisoner in Annam. After his capture, his brother, Che Da A Ba, was assigned to govern Champa by the Dai Viet.
