Jayakatwang (died 1293) was the king of short lived second Kingdom of Kediri (also known as Gelang-gelang Kingdom) of Java, after his overthrow of Kertanegara, the last king of Singhasari. He was eventually defeated by Raden Wijaya, Kertanegara's son-in-law using the troops of the Mongol Yuan dynasty that were invading Java. Raden Wijaya would later turn against the Mongols and found Majapahit, the greatest empire in Java.
