The Chandiranaar Temple (also called Kailasanathar temple or Thingalur temple) is a Hindu temple in the village of Thingalur, 33 kilometres (21 mi) from Kumbakonam on the Kumbakonam - Thiruvaiyaru road in the South Indian state of Tamil Nadu. The presiding deity is Soma (moon).
However, the main idol in the temple is that of Kailasanathar or Shiva. The temple is considered one of the nine Navagraha temples in Tamil Nadu. Thingalur is the birthplace of Appothi Adigal, one of the 63 nayanmars of lord Shiva and an ardent devotee of saint Thirunavukkarasar, though the temple has no assets related to the saint.
The temple has four daily rituals at various times from 6:00 a.m. to 8:30 p.m., and four yearly festivals on its calendar. Mahasivarathri, Margazhi Thiruvadirai, Panguni Uthiram and Thirukartigai are the major festivals celebrated in the temple.
The village finds cursory mention in the 7th century Tamil Saiva canonical work, the Tevaram, written by Tamil saint poets known as the Nayanars and classified as Vaippu Sthalam.
