Kalinga is a landlocked province of the Philippines in the Cordillera Administrative Region in Luzon. Its capital is Tabuk and borders Mountain Province to the south, Abra to the west, Isabela to the east, Cagayan to the northeast, and Apayao to the north. Prior to 1995, Kalinga and Apayao used to be a single province named Kalinga-Apayao, until an ethnic/tribal war prompted separation.
