Intharacha, also spelled In Racha (Thai: อินทราชา, Indrarājā), also known as King Nakhon In (Thai: เจ้านครอินทร์, RTGS: Chao Nakhon In), was the sixth king of the Ayutthaya Kingdom, reigning from 1409 to 1424. A member of the Suphannaphum Dynasty, he successfully consolidated his dynasty's power and expanded Ayutthaya's influence over the Sukhothai Kingdom.
Intharacha is notably recognized in Chinese records for his strong diplomatic ties with the Ming Dynasty, having personally visited the Chinese court twice. His reign effectively ended a period of political instability within Ayutthaya. Following his death in 1424, a succession struggle between his eldest sons led to the accession of his third son, Borommarachathirat II (Chao Sam Phraya).
