Loganatha Perumal Temple, Hindu temple in Thirukannagudi, India.

The Loganatha Perumal Temple is a Hindu shrine dedicated to Vishnu, located near Thirukannagudi in Tamil Nadu, India. It features a five-tiered entrance tower known as a gopuram, granite walls, and detailed stone carvings in the Dravidian style.

The temple was built during the late Chola period, following the building traditions of that medieval South Indian dynasty. Rulers from the Vijayanagara empire and the Madurai Nayaks later expanded the complex, giving it the form it has today.

The temple is one of the Panchakanna (Krishnaranya) Kshetrams, five holy places named for Krishna, who is not the presiding deity at any of them; the processional deity gave the sites their names. Tirumalisai Alvar sang of this shrine in one hymn of the Nalayira Divya Prabandham, and the Panguni Brahmostavam in the Tamil month of Panguni (April–May) is its main yearly festival.

The temple is open year-round, and early morning or evening visits tend to be quieter than midday. Visitors are expected to remove footwear before entering, so comfortable shoes that are easy to slip on and off are a good choice.

Local tradition holds that the sage Vasishtha fashioned a butter figure of Krishna at this spot, leading to a divine encounter beneath a Magizha tree. That tree is still considered a sacred point within the temple grounds and draws the attention of many pilgrims today.
