Tangalle is a big town in Hambantota District, Southern Province, Sri Lanka, governed by an Urban Council. It is one of the largest towns in southern province. It has a mild climate, in comparison to the rest of the district, and sandy beaches.
The name of the town in Sinhala means "projected rock", a reference to the rocks which form the coastline in the town area, which contrasts with the sandy beach of the surrounding areas.
Tangalle is a regionally important fishing port and a centre of tourism. In the city centre there is an old Dutch fort which is used as a prison today.
The town also serves as a starting point for visits to the rock temple of Mulkirigala.
