The Bhu Varaha Swamy temple is a Hindu temple, located at Srimushnam, in the South Indian state of Tamil Nadu. Constructed in the South Indian style of architecture, the temple is dedicated to Varaha (Bhu Varaha Swamy), the boar-avatar of the god Vishnu and his consort Lakshmi as Ambujavalli Thayar. It is Classified one among the 108 Abhimana Kshethram of Vaishnavate tradition. One of the greatest Hindu scholars of Vaishnava Tattvavada (Dvaita) philosophy, Madhvacharya, have come and resided in this temple many times.

The temple is associated with Varaha, the boar avatar of Vishnu. The asura king Hiranyaksha stole the earth and took it to his realm of the netherworld. The earth-goddess Bhudevi prayed to Vishnu to rescue her. Pleased, Vishnu appeared here in the form of Varaha, a boar, killed the asura. The sweat of Sri Bhuvaraha Swamy dropped here, creating the temple tank (Nithya Pushkarani). In his dying wish, the asura king asked Vishnu to turn towards his direction; Vishnu obliged. The central icon faces towards the asura in the south, while his human body faces the devotees in the West. The festival icon, Yagya Varahaswamy, as requested by Bhudevi displays the regular features of Vishnu with his conch and chakra in his hands.As per another legend, a local Nawab on the county was ailing with Carbuncle and was given up by all the doctors. He is believed to have prayed Bhuvaraha and was cured off all his ailments. He made generous contributions to the temple and was later named Bhura Sahib. Each year the deity is taken to the village when his descendants make offerings to the deity.

The temple is considered one of the eight Sywayambu Kshetras of Vishnu where presiding deity is believed to have manifested on its own. Seven other temples in the line are Srirangam Ranganathaswamy temple, Tirumala Venkateswara Temple, and Vanamamalai Perumal Temple in South India and Saligrama, Naimisaranya, Pushkar and Badrinath Temple in North India.Divine ablution is performed daily for the presiding deity, unlike other Vishnu temples where it is performed only occasionally. In Tirumala, devotees are supposed to visit the Bhu Varaha temple before they worship Lord Venkateshvara but in Srimushnam devotees visit the Srinivas temple in the western entrance before visiting Bhu Varaha Swamy. The temple is frequented by childless couple seeking children and unmarried people seeking marriage. The local belief is that the worship done to Saptha Kannigaigal in the temple leads to right match.Te temple is counted as Abhibana Stalas, the temples that are closer to the heart of Vishnu.
