Ramanathaswamy Temple is a Hindu temple dedicated to the Hindu god Shiva located on Rameswaram island in the state of Tamil Nadu, India. It is also one of the twelve Jyotirlinga temples. It is one of the 275 Paadal Petra Sthalams, where Nayanars (Saivite saints), Appar, Sundarar and Tirugnana Sambandar, have glorified the temple with their songs. The Lingam of Ramanathaswamy (Shiva), was established and worshiped by Shri Rama Swamy, after he came back from present-day island of Sri Lanka. It is one of the Char Dham pilgrimage sites. The temple was expanded during the 12th century by the Pandya Dynasty, and its principal shrine’s sanctum was renovated by Jeyaveera Cinkaiariyan and his successor Gunaveera Cinkaiariyan, monarchs of the Jaffna kingdom. The temple has the longest corridor in the world. It was built by King Muthuramalinga Sethupathiy. The temple, located in Rameswaram, is considered a holy pilgrimage site for Shaivites, Vaishnavites and Smarthas.

There are sixty-four Tīrthas or Tirthams (holy water bodies) in and around Rameswaram. According to the Skanda Purana, twenty-four of them are important. Of the 24, Twenty Two are in the form of tanks and wells within the precincts of the temple. Bathing in these tanks is a major aspect of the pilgrimage to Rameswaram and is considered equivalent to penance. Twenty-two of the tanks are within the Ramanathaswamy Temple. The foremost one is called Agni Tirtham, the sea (Bay of Bengal). Jatayu, a vulture/eagle demigod, is believed to have fought in vain with the rakshasa-king Ravana to save Sita, and is said to have fallen down at Jatayu Tirtham, as his wings were severed. Villoondi Tirtham literally translates to 'buried bow', is located around 7 kilometres from the main temple on the way to Pamban. It is believed to be the place where Rama quenched the thirst of Sita by dipping the bow into the sea water. Other major holy bodies are Hanuman Tirtham, Sugriva Tirtham, and Lakshmana Tirtham.
