Jaya Indravarman IV was the king of Champa, a former region located within modern-day Vietnam, from 1167–1192. He probably was the same person as Panduranga ruler, Po Klong Garai. A usurper, "he called himself Jaya Indravarman on Vatu and said he came from the 'famous place known by the name Gramapuravijaya." He was "full of energy, courage and pride...well versed in all the shastra." He sent tribute to the Court of China and the Dai Viet. Unsuccessful in purchasing horses from China for an overland invasion, he prepared a squadron of water vessels.
