San Gabriel was formerly known as sitio “Baka-Burnotan”, derived from “binnornutan”. The sitio was the meeting place of both Christians and pagan Kankanaey settlers from nearby sitios to graze their cattle while playing the game. The name was later shortened to "burnotan". The wide plain and fertile soil attracted Christian and pagan settlers, who later intermarried which led to the increase in population. On April 19, 1897, a Roman Catholic priest Father Redondo established a church in the area and introduced the patron saint to be Saint Gabriel, from which the town was later named. In 1906, San Gabriel was made into a township under the sub-province of Amburayan in Mountain Province, with the first Presidente being Don Pablo Waggay. The township was converted into a municipal district of Amburayan in 1920, and into a municipality in 1922, following the settlement of a boundary dispute between La Union and Mountain Province. In 1947, San Gabriel was converted into a regular municipality by virtue of Executive Order No. 72 issued by PresidentManuel Roxas through the sponsorship of former House Speaker Pro-Tempore Francisco Ortega.
