The Chico River Dam Project was a proposed hydroelectric power generation project involving the Chico River on the island of Luzon in the Philippines that locals, notably the Kalinga people, resisted because of its threat to their residences, livelihood, and culture. The project was shelved in the 1980s after public outrage in the wake of the murder of opposition leader Macli-ing Dulag. It is now considered a landmark case study concerning ancestral domain issues in the Philippines.
