Ahungalla is a small coastal town, located in Galle District, Southern Province, Sri Lanka, governed by an Urban Council.

It is approximately 76.6 kilometres (47.6 mi) south of Colombo and is situated at an elevation of 12 metres (39 ft) above the sea level.

Ahungalla is known primarily for its sandy beach, accompanied by a wide palm belt, considered to be one of the best on the island.

The largest and most well-known building in the town is the luxury hotel, Heritance Ahungalla[2] (formerly Hotel Triton), designed by notable Sri Lankan architect, Geoffrey Bawa, and constructed from 1979 to 1981.

As with the entire region Ahungalla was devastated by the tsunami caused by the 2004 Indian Ocean earthquake.
