Suryanar Kovil (also called Suryanar Temple) is a Hindu temple dedicated to the deity Hindu Sun-God, located in Suryanar Kovil, a village near the South Indian town of Kumbakonam Thanjavur District in Tamil Nadu, India. The presiding deity is Suriyanar, the Sun and his consorts Ushadevi and Pratyusha Devi. The temple also has separate shrines for the other eight planetary deities. The temple is considered one of the nine Navagraha temples in Tamil Nadu. The temple is one of the few historic temples dedicated to Sun god and is also the only temple in Tamil Nadu which has shrines for all the planetary deities.

The present masonry structure was built during the reign of Kulottunga Choladeva (1060-1118 CE) in the 11th century with later additions from the Vijayanagar period. Constructed in the Dravidian style of architecture, the temple has a five-tiered rajagopuram, the gateway tower and a granite wall enclosing all the shrines of the temple.

It is believed that the planetary deities were cursed by Brahma to dwell in Vellurukku Vanam, the white wild flower jungle and were blessed by Shiva to make it their abode to devotees. The temple has six daily rituals at various times from 5:30 a.m. to 9 p.m., and two yearly festivals on its calendar. The temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu.

Legend
As per Hindu legend, Sage Kalava was suffering from serious ailments along with leprosy. He prayed to the Navagrahas, the nine planet deities. The planets were pleased by his devotion and offered cure to the sage. Brahma, the Hindu god of creation, was angered as he felt that the planets have no powers to provide boons to humans. He cursed the nine planets to suffer from leprosy and were sent down to earth in Vellurukku Vanam, the white wild flower jungle. The planets prayed to Shiva to relieve them off the curse. Shiva appeared to them and said that the place belonged to them and they would have to grace the devotees worshipping them from the place. This is the only temple where there are separate shrines for each of the planet deities. It is also the only temple among the nine planetary temples where Shiva is not the presiding deity.

History
It is stated in one of the inscriptions found in the temple that it was built in the reign of Kulottunga Choladeva (1060-1118 CE) and was called Kulottungachola-Marttandalaya.

The temple is mentioned in the songs of Muthuswami Dikshitar, who has composed a song starting with "Suryamurthe" in Saurashatra ragam.

Religious importance
The temple is one of the nine Navagraha temples of Tamil Nadu and is a part of the popular Navagraha pilgrimage in the state - it houses the image of Surya (Sun). The planets are believed to influence the horoscope computed based on time of one's birth and subsequently influence the course of life. Each of the planets are believed to move from a star to another during a predefined period and thus sway over an individual's fortunes. Kol vinay theertha Vinayagar is an important deity inside the temple and should be worshiped first before worshiping Lord Suriyan and other planets

. The Navagrahas, as per Hindu customs, are believed to provide both good and bad effects for any individual and the bad effects are mitigated by prayers. As in other Navagraha temples, the common worship practises of the devotees include offering of cloth, grains, flowers and jewels specific to the planet deity. Lighting a set of lamps is also commonly followed in the temple. As per contemporary Saivite belief, the energies distributed cyclically by Navagrahas can be channeled based on remedial measures. As per local legends, Shiva, the overlord of the nine planetary deities, allowed them to freely grant wishes based on devotion of the devotees.

According to Hindu legend, Mahalingaswamy is the centre of all Shiva temples in the region and the Saptha Vigraha moorthis (seven prime consorts in all Shiva temples) are located at seven cardinal points around the temple, located in various parts of the state. The seven deities are Nataraja in Chidambaram Nataraja Temple at Chidambaram, Chandikeswarar temple at Tirucheingalur, Vinayagar in Vellai Vinayagar Temple at Thiruvalanchuzhi, Muruga in Swamimalai Murugan Temple at Swamimalai, Bhairava in Sattainathar Temple at Sirkali, Navagraha in this temple and Dakshinamoorthy in Apatsahayesvarar Temple at Alangudi, Nannilam.
