The Legislative district of Ifugao is the representation of the province of Ifugao in the of the Philippines. The province is currently represented in the lower house of the Congress of the Philippines through its lone congressional district.
In 1917 the undivided Mountain Province, of which Ifugao was a component sub-province, was provided representation in the Philippine Legislature. Pursuant to the Revised Administrative Code (Act No. 2711) enacted on 10 March 1917, the non-Christian-majority areas of the Philippines, which then included the Mountain Province, were to be collectively represented in the legislature's upper house by two senators from the 12th senatorial district, both appointed by the Governor-General. Three assembly members, also appointed by the Governor-General, were to represent the Mountain Province and the chartered city of Baguio in the lower house as a single at-large district.
The residents of Ifugao and the rest of the Mountain Province only began electing representatives through popular vote in 1935 by virtue of Act No. 4203; the law provided the territorial coverage for each lower house representative district, while also abolishing the senatorial district system. The sub-province was then represented as part of the Mountain Province's third district.
