The Kotmale River (Sinhalese: කොත්මලේ ඔය ) is a tributary of the Mahaweli River, and is the fourth longest river in Sri Lanka. The river begins as the Agra Oya, in the Horton Plains in the Central Highlands. The Central Plains have an annual rainfall of between 125 and 200 inches a year. The river is about 70km (43.3 miles) long and drains a basin of about 58,534 ha (226 square miles). The river flows through a traditional area of ancient villages and tea plantations. King Dutugemunu spent his youth here. The Kotmale Oya flows into the Mahaweli shortly after the town of Nawalapitiya. Tributaries of the Kotmale Oya include the Nanu Oya River, the Pundul Oya, the Puna Oya and the Dambagastalawa Oya.

The river was dammed between 1979 and 1985 as part of a hydro-electric project within the Accelerated Mahaweli Ganga scheme. The opening ceremony took place in August 1985. Some 3,000 families had to be relocated top higher ground. The area has a history of geological instability.
