The Maskeliya Oya (translated into Maskeliya River from Sinhala) is a major upstream tributary of the Kelani River in Sri Lanka. This long tributary originates in the hills of the Peak Wilderness Sanctuary, before passing through the Maskeliya Reservoir. The Maskeliya Oya converges with the Kehelgamu Oya at Kalugala, forming the long Kelani River. The river is heavily used for hydroelectric power generation.

Features on the river The following table lists the major features along the Maskeliya Oya, from its origins further upstream. Some dams hold back water, and transfer a percentage of it to hydroelectric power stations located further downstream, via tunnels.
