Mountain Province (Filipino: Lalawigang Bulubundukin), is a landlocked province of the Philippines in the Cordillera Administrative Region in Luzon. Its capital is Bontoc. Mountain Province was formerly referred to as Mountain in some foreign references. The name is usually shortened by locals to Mt. Province. The province was named so for being in the Cordillera Central mountain range found in the upper realms of Luzon island. Mountain Province was also the name of the historical province that included most of the current Cordillera provinces. This old province was established by the Philippine Commission in 1908, and was later split in 1966 into Mountain Province, Benguet, Kalinga, Apayao and Ifugao. The province is also known for its mummy caves, which contain naturally mummified bodies, and for its hanging coffins.
