Watrap is a taluk in Virudhunagar District, in the Indian state of Tamil Nadu.

Watrap's traditional name before the British came was Vatratha Iruppu, which translates as "surplus water".

The holy uphill shrine "Sundara Mahalingam (Lord Shiva) temple" (also known as Thaani Paarai and Sathuragiri Malai) is there.

A Krishna, Rukmini and Sathyabama temple called Gopala Swamy Malai tops a small hill, 22 km from Watrap.

Natural caves, some 2 km away from Sathuragiri temple and a fresh water pond at the top of the hill attract visitors.
