The Sri Lanka Lowland Rain Forests represents Sri Lanka's Tropical rainforests below 1,000 m in elevation in the southwestern part of the island. The year-around warm, wet climate together with thousands years of isolation from mainland India have resulted in the evolution of numerous plants and animal species that can be only found in rain forests in Sri Lanka.

The thick forest canopy is made up of over 150 species of trees, some of the emergent layer reaching as high as 45 m. The lowland rain forests accounts for 2.14 percent of the Sri Lanka's land area. Sri Lanka has the highest density of amphibian species worldwide. Many of these including 250 species of tree frogs live in these rain forests.
