Agniswarar Temple, Kanjanur, Hindu temple in Kanjanur, Tamil Nadu, India.

Agniswarar Temple in Kanjanur has a five-tier rajagopuram and two prakarams. The tower's base is a pale yellow band with a projecting eave; above it, carved figures are painted blue, red, green, yellow and gold, and a central niche holds a white bull. A red, white and blue banded pillar stands at street level.

The temple was built by the Medieval Cholas and later renovated by kings of the Vijayanagar Empire. It is counted among the temples on the northern bank of the Kaveri, the 36th in the Chola-country series revered in the Tevaram. Appar and Sundarar sang its praises, and it belongs to the Madurai Adheenam.

The temple is one of the seven shrines of the Thirukkanjanur Sapthasthanam, a circuit that also links Thirukodikkaval, Thiruvalangadu, Thiruvavaduthurai, Aduthurai, Thirumangalakkudi and Thirumanthurai. It is revered in the Thevaram verses of Appar and Sundarar, and the sage Kanjanar is held to have been born here. The temple tree is the purasa (silk-cotton) tree, and devotees believe that circling it sixteen times over one mandala period removes debt troubles.

Visitors can reach the sanctuary by regular bus services from Thanjavur to Kanjanur, operating throughout the day from early morning to evening. Food and supplies are available near the temple site, as the area is well-connected to the town.

Sukra has no separate shrine here: the temple holds that Shiva himself appears as Sukra, so the planet is worshipped within the Agniswarar idol. Devotees also walk around the sacred tree, the purasa (flame-of-the-forest), sixteen times over one mandala period, a practice believed to clear debt troubles.
