The Cordillera Peoples' Alliance (CPA) is an alliance of indigenous peoples organizations, advocate groups and organizations, as well as sectoral organizations in the central mountain region of Northern Luzon, Philippines. It was formally constituted by 27 peoples' organizations during a Congress in Bontoc, Mountain Province in June 1984.

The CPA's founding is a crucial step towards uniting the Cordillera indigenous peoples in defense of their ancestral land, in their struggle for self-determination, and in uniting with the rest of the Filipino people in the struggle for national freedom and genuine democracy.

The CPA's membership today includes human rights and church organizations, sectoral organizations of women, farmers, youth, students, workers, and other urban poor; rural community organizations and peace pact holders representing several villages, clan and tribal groups. Today, it stands as the biggest people's organization in the entire Cordillera region.

In seeking to arouse, organize and mobilize the largest number of people for the defense of the Cordillera peoples' ancestral lands, for self-determination and for national democracy, the CPA established various Commissions. In 1991, the CPA Youth Commission was established.
