Kalinga is a landlocked province of the Philippines in the Cordillera Administrative Region of Luzon.
Its capital is Tabuk and borders Mountain Province to the south, Abra to the west, Isabela to the east, Cagayan to the northeast, andApayao to the north.
Kalinga and Apayao are the result of the 1995 partitioning of Kalinga-Apayao; this was to better service the respective needs of the various indigenous peoples in the area.
The topography of Kalinga province is rugged and sloping, with mountain peaks ranging from 1,500 to 2,500 metres (4,900 to 8,200 ft) in elevation. The province’s western side is characterised by sharp, crested, interlinking peaks of steep slopes, isolated flatlands, plateaus and valleys. The eastern lands are mainly of rolling and gradually sloping foothills.
Large swaths of the province's lowlands are open grassland suitable for pasture, while the highlands have extensive areas of tropical rainforest. In higher elevations to the west, particularly in the mountains of Balbalan, lie some of the most intact pine forests of Luzon island. Rizal and Tabuk with their flatlands are the biggest rice producers. Next in rice production are the mountainous area, and of note are the rice terraces of Balbalan, Lubuagan, Pasil, Pinukpuk, Tinglayan, and Tanudan.
The 7 municipalities and 1 city of the province comprise a total of 152 barangays, with Bulanao in Tabuk City as the most populous in 2010, and Anggacan Sur in Tanudan as the least. If cities are excluded, Pinukpuk Junction in Pinukpuk municipality has the highest population.
