A plebiscite for the ratification of the organic act creating the Cordillera Autonomous Region was held on January 30, 1990, to ask if the voters in the Cordillera Administrative Region wanted to be an autonomous region under Republic Act No. 6766. The Cordillera Administrative Region (CAR) consists of the provinces of Abra, Benguet, Ifugao, Kalinga-Apayao, and Mountain Province, and the city of Baguio. Only Ifugao voted in favor of autonomy, and a Supreme Court case later disallowed the creation of an autonomous region with just one province.

This was the first attempt by the Cordillera autonomy movement to create an autonomous region after years of conflict by the Cordillera People's Liberation Army. A second plebiscite in 1998 resulted in Apayao (by then separated from Kalinga) voting for autonomy, and an establishment of an autonomous region still failed.
