Jayanegara or Jayanagara (formal regnal name Sri Maharaja Wiralandagopala Sri Sundarapandya Dewa Adhiswara, or Sri Sundarapandyadevadhisvara Vikramottungadeva, also known as Kala Gemet), Prince of Kediri in 1295, reigned from 1309 to 1328, was a Javanese King and the second monarch of Majapahit empire. Jayanegara was the heir, crown prince, the son of Raden Wijaya, the founder of Majapahit. The story of his life was written in several records, including Pararaton and Negarakertagama. His reign saw the beginning of Gajah Mada's rise as an important figure in the empire.

Raden Wijaya took all of Kertanegara's four daughters hands in marriage. The siblings were Tribhuwaneswari the oldest also the queen, Prajnaparamitha, Narendra Duhita, and Gayatri Rajapatni the youngest. The reasons of Raden Wijaya's practice of siblings polygamy was to ensure his claim of legitimacy, also to prevent the contest for Kertanegara's Singhasari legacy. Raden Wijaya also took Indreswari (also known as Dara Petak), the princess of Malayu Dharmasraya Kingdom whom brought to Majapahit court from Sumatra through Kertanegara's Pamalayu expedition. Reden Wijaya or Prince Nararya Sangramawijaya ascends to Majapahit throne as King Kertarajasa Jayawardhana.

Jayanegara was King Kertarajasa's son, his name in Sanskrit-derived Old Javanese words: jaya ("glorious") and nagara ("city" or "nation"), which means "glorious nation". Without any doubt Prince Jayanegara was a legitimate son of Raden Wijaya. However, there are several versions concerning Jayanegara's mother. Some earlier historian consider him as the son of Queen Tribhuwaneswari (not to be confused with Tribhuwana Wijayatunggadewi, Jayanegara's half-sister daughter of Gayatri Rajapatni), thus he earn the right to become the crown prince. However, according to Pararaton, Jayanegara was Wijaya's son from Dara Petak, princess of Malayu Dharmasraya. While Queen Tribhuwaneswari and most of her sisters are childless, only Gayatri Rajapatni has two daughters; Tribhuwana Wijayatunggadewi and Rajadewi. To reconcile this facts, some historian suggested that Jayanegara was Dara Petak's son adopted by childless Queen Tribhuwaneswari and raised as her own.
