Mountain Province is sometimes incorrectly named Mountain in some foreign references. The name is also incorrectly shortened by locals to Mt. Province, which in turn is read by native Anglophones as "Mount 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 area of the Cordillera mountains proved difficult to control by the Spaniards. From 1566 to 1665, they sent expeditions to conquer the land but the rugged terrain and hostile indigenous population at the time were major obstacles to complete subjugation.

In August 19, 1908, during the American rule, the Philippine Commission enacted Act No. 1876, which organized the entire area of the Cordilleras into one large province, named Mountain Province. The first governor was Samuel Cane, and the town of Bontoc was made the capital. It was originally composed of the sub-provinces of Amburayan, Apayao, Benguet, Lepanto-Bontoc, Ifugao and Kalinga. Amburayan was later abolished in 1920 and its corresponding territories were transferred to the provinces of Ilocos Sur and La Union. Lepanto was also reduced in size and its towns were integrated into the sub-provinces of Bontoc and Benguet, and to the province of Ilocos Sur. 
|Amburayan||Yes, in 1920||Territories annexed to Ilocos Sur and La Union ||Ifugao||No|
|Benguet||No||Eastern towns annexed to Ilocos Sur and La Union in 1920||Lepanto-Bontoc||Yes, in 1920||Territories annexed to Ilocos Sur, Bontoc and Benguet|
Effective on April 7, 1967, Republic Act No. 4695 abolished the old Mountain Province, converting its sub-provinces into 4 independent provinces: Benguet, Ifugao, Kalinga-Apayao and Mountain Province (corresponding to the former Bontoc sub-province). On June 15, 1987, the Cordillera Administrative Region was established upon the issuance of Executive Order 220 by then-President Corazon Aquino, and Mountain Province was made one of its provinces. 
It has an area of 215,738 hectares (533,100 acres), with 83% mountainous while 17% make up hills and levels. The province has many rivers, waterfalls, mountains, and caves. The central and western areas of the province are characterized by rugged mountains and steep cliffs, while the eastern portion has generally sloping terrain.
