Azhagiya Manavalan Perumal Temple (also called Thirukozhi or Nachiyar Koil) in Woraiyur, a suburb Tiruchirappalli in the South Indian state of Tamil Nadu, is dedicated to the Hindu god Vishnu. Constructed in the Dravidian style of architecture, the temple is glorified in the Divya Prabandha, the early medieval Tamil canon of the Azhwar saints from the 6th - 9th centuries AD.
It is one of the 108 Divyadesam dedicated to Vishnu, who is worshipped as Azhagiya Manavalan and his consort Lakshmi as Kamalavalli.
Azhagiya Manavalan is believed to have appeared to Kamalavalli, the daughter of Chola king Nanda Cholan, in this place to marry her. Six daily rituals and three yearly festivals are held at the temple, of which the chariot festival, celebrated during the Tamil month of Chittirai (March - April), is the most prominent.
