Kertawijaya or Dyah Kertawijaya was the seventh monarch of Majapahit reigning from 1447 to 1451 by the regnal name Sri Maharaja Wijayaparakramawardhana.

Prince Kertawijaya succeeded his older sister Suhita in 1447 due to royal prerogative.

Pāduka srī mahārāja, srī sakala-yawa-rājādhirāja paraméswara srī bhattāra prabhu Wijayaparākramawarddhānanāmarājābhiseka garbbaprasutināma Dyah Krtawijaya
His Majesty the Maharaja, the King of kings of the whole Java and Supreme Lord, the august Sovereign whose regnal name was Wijayaparakramawardhana and his birth name was Dyah Kertawijaya

Natural disasters frequently occurred during his reign, including earthquakes and volcanic eruptions. One famous incident was Tidung Gelanting's killing, led by his nephew Prince of Paguhan, son of the Prince of Tumapel.

When the Majapahit Kingdom was in chaos due to civil war, moral decline, and rampant gambling, robbery, and rape, Dyah Kertawijaya invited the Sufi saint Sunan Ampel to help improve the behavior of the people. He then introduced the Moh Limo teachings.

Brawijaya is the name or title of a well-known Majapahit king for modern Javanese people under some manuscripts written in the next era.

A tomb of a princess of Champa found in Mojokerto with the year of 1448 led the Javanese to believe that she was one of King Brawijaya's principal wives. In addition, the name of Kertawijaya as the ancestor of Raden Patah was found in Queen Kalinyamat's tomb located in Jepara.

Another story told that King Brawijaya's wife was a Muslim's queen Dwarawati of the Champa Kingdom. In contrast, Pararaton mentioned that Dyah Kertawijaya's wife was the Princess of Daha, referred to Jayawardhani (personal name Dyah Jayeswari) in the Waringin Pitu charter (1447), a daughter of his aunt Rajasawardhani, by whom he had married when he was still the Prince of Tumapel. This was proven by the Pararaton passage mentions the children of King Wikramawardhana, followed by the children of the Prince of Pandan Salas (husband of Rajasawardhani).
