Mountain Province's at-large congressional district is the sole congressional district of the Philippines in the Mountain Province. It was first created in 1916, when the province was first granted legislative representation in the House of Representatives under the Philippine Autonomy Act, also known as the Jones Law. The district was initially composed of the sub-provinces of Amburayan, Apayao, Benguet, Bontoc, Ifugao, Kalinga, and Lepanto, together with the independent city of Baguio and the municipalities and municipal districts that had been transferred to the provinces of Cagayan, Ilocos Sur, and La Union, with three members appointed by the governor-general serving as representatives of the province, although they did not need to be residents of the areas they represented. The Spanish politico-military district of Bontoc, which would later become a sub-province during the American period, was earlier represented in the Malolos Congress of the First Republic by a delegate appointed by the president.

In 1935, the district was divided into three separate single-member districts for the Commonwealth National Assembly, serving from 1935 to 1941. The three districts would later be dissolved into one two-member at-large districts for the National Assembly of the Second Republic. The district was later re-created in 1966 following the division of the greater Mountain Province into the provinces of Benguet, Ifugao, Kalinga-Apayao, and a smaller Mountain Province, and reverted to a single-member district for the last legislature of the House of Representatives prior to the imposition of martial law from 1969 to 1972.

The district served as an electoral district in the 1934 Constitutional Convention, with two delegates representing each sub-province, and in the 1971 Constitutional Convention, with two delegates representing Mountain Province at-large.

Following the ratification of the 1973 Constitution and the shift to a parliamentary system, districts were replaced by multi-member regional constituencies, with Mountain Province incorporated into Region I's at-large district for the Interim Batasang Pambansa. When provincial and city district representation was restored in 1984 for the Regular Batasang Pambansa, Mountain Province was represented by one assemblyman. The district was later re-created for the re-established House of Representatives in 1987. It is currently represented in the 20th Congress by Maximo Dalog Jr. of the Nacionalista Party.
