The Rameshvara Temple (also spelt Rameshwara or Ramesvara) is located in the town of Narasamangala of Chamarajanagar district, Karnataka state, India.

The temple was constructed during the 9th century rule of the Western Ganga Dynasty of Talakad.

[1] The temple plan is simple, yet it has a unique superstructure (tower or shikara) that is made of brick and stucco.

Some of the remarkable sculptures in the temple include that of Nataraj (a form of the Hindu god Shiva), saptamatrikas (the seven Hindu goddesses) and the Ganga king seated in state with his queen by his side.

This is attested to by the two Kannada language inscriptions tablets (1291-1343 A.D) on the site that describes grants made by King Veera Ballala III to the local deity Ramanathadeva of Narasamangala.
