Tukad Daya is a river located in Buleleng, north of the island of Bali.

The 40 km long river originates from its headwaters around Kintamani, north of the highland ridge stretching between the northwest slope of the Batur caldera and the east slope of the Bratan caldera.

Generally, the topography of the Tukad Daya basin consists of steep slopes from two mountains range, namely Mount Batur and Bratan, and gradually descends around the northern coast in Bungkulan.

Additionally, it functions as a Micro Hydro Power Plant capable of generating 0.54 MW of electricity.
