The Jagannath Temple is a Hindu temple dedicated to the god Jagannath, a form of Vishnu in Hinduism. It is located in Puri in the state of Odisha, situated on the eastern coast of India. As per temple records, King Indradyumna of Avanti built the main temple of Jagannath at Puri. The present temple was rebuilt from the eleventh century onwards, on the site of the pre-existing temples in the compound, but not the main Jagannath temple, and begun by Anantavarman Chodaganga, the first king of the Eastern Ganga dynasty. Many of the temple rituals are based on Oddiyana Tantras which are the refined versions of Mahayana Tantras as well as Shabari Tantras which are evolved from Tantric Buddhism and tribal beliefs respectively. The local legends link the idols with aboriginal tribes and the daitapatis (servitors) claim to be descendants of the aboriginals. The temple is one of the 108 Abhimana Kshethram of the Vaishnavite tradition.

The temple is famous for its annual Ratha Yatra, or chariot festival to honor the three gods, in which the three principal deities are pulled on huge and elaborately decorated raths, or temple cars. The worship is performed by the Bhil Sabar tribal priests, as well as priests of other communities in the temple. Unlike the stone and metal icons found in most Hindu temples, the image of Jagannath is made of spruce wood, and is ceremoniously replaced every 12 or 19 years by an exact replica. The temple is one of the Char Dham pilgrimage sites. It is also famous because many legends believe that Krishna's heart was placed here, and the material that it is made from damages the heart, so they have to change it every seven years.

The temple is sacred and holy to all Hindus, and especially in those of the Vaishnava traditions. Many great Vaishnava saints, such as Ramanujacharya, Madhvacharya, Nimbarkacharya, Vallabhacharya and Ramananda were closely associated with the temple. Ramanuja established the Emar Matha in the south-eastern corner of the temple, and Adi Shankaracharya established the Govardhan Math, which is the seat of one of the four Shankaracharyas. It is also of particular significance to the followers of Gaudiya Vaishnavism, whose founder, Chaitanya Mahaprabhu, was attracted to the deity, Jagannath, and lived in Puri for many years.
