Srirangam (Tamil: ஸ்ரீரங்கம்), Old name is Vellithirumutha gramam and Tamil name is Thiruvarangam (Tamil: திருவரங்கம்), is an island and a part of the city of Tiruchirapalli (also known as Trichy or Tiruchi), in South India.

Srirangam is bounded by the Kaveri River (also known as Cauvery river) on one side, and the Kaveri distributary Kollidam (Coleroon) on the other side. Srirangam is home to a significant population of Srivaishnavites (followers of Lord Vishnu, one of the triumvirate of Hindu Gods the other two being Lord Siva, the Destroyer and Lord Brahma, the Creator).

Srirangam is a native of a notable personality of Tamil Nadu, Jayalalitha Jayaram, where she had contested and won in State Assembly elections, 2011.

Srirangam is famous for its Sri Ranganathaswamy Temple, a major pilgrimage destination for Hindus (especially Srivaishnavites) and the largest temple complex in India.

According to the temple's website, Srirangam can be considered the biggest functioning Hindu temple in the world as it covers an area of about 631,000 square metres (6,790,000 sq ft) with a perimeter of 4 km (10,710 ft). Srirangam claims to be the biggest functioning temple, because Angkor Wat is the biggest but non-functioning Hindu temple in the world.
