Kurumathur inscription (871 AD), also romanised as Kurumattur, is a mid-9th century inscription from Kurumathur, near Areacode in Kerala, south India. The Sanskrit inscription in Pallava Grantha script is engraved on a loose granite slab from the Kurumathoor Vishnu temple.^[1][2][3] It is one of the rare Sanskrit inscriptions from Kerala.^[1]

The inscription relates to the rule of Chera Perumal king Rama Rajasekhara (9th century AD) in north-central Kerala.^[1][4] It is dated to 24 May 871 AD as a Kali Day chronogram.^[4] Composed in shardula-vikridita metre in Sanskrit, the three-stanza inscription states that the king Rajasekhara belonged to the illustrious Ikshvaku dynasty of god Rama.^[2] It wishes that king Rajasekhara's glory be spread across the oceans. Further, he is extolled as having ruled the country with justice and never deviated from the Laws of Manu.^[2] During his righteous rule twelve Brahmanas constructed a temple pond and also installed an idol of god Vishnu in the temple.^[2][3]

The record was excavated during a renovation of Kurumathoor Vishnu temple (south of Areacode) in February, 2011.^[2][3] The discovery of the inscription was reported by M. R. Raghava Varier.^[1]
