It is where the infamous Battle of Balete Pass where Brigadier General James Dalton II was killed during the Second World War.

According to the official website of Santa Fe, Nueva Vizcaya, the town's former name "Imugan" derives from the combination of "imug", a Kalanguya word and "gone", an English term, both of which have the same meaning, while the current name was derived from the town's patron saint San Jose de Santa Fe.

The town's original inhabitants were the Kalanguya, an ethnic minority belonging to the Igorot people then later on followed by the Ilocanos, Pangasinenses and the Tagalogs.

Santa Fe was formerly an Igorot settlement during the Spanish era called Imugan. It was one of the settlements discovered during the mission of Ituy, which later became part of the jurisdiction of the Commandancia of Kayapa. It became part of Aritao before it finally stood independently as a town.

The Municipal district of Imugan was founded by Governor-General Francis Burton Harrison in 1917 by virtue of Executive Order No. 39. The first appointed municipal president was a certain Kalanguya chief named Licodan who served until 1910.

On November 7, 1923, the Route 5 also known as San Jose–Santa Fe Road (Now part of the Maharlika Highway) was informally opened allowing easy access from Central Luzon to the Cagayan Valley.

During the Second World War, the Japanese Imperial Army established a puppet government in the country. Two strategic locations, Dalton Pass in Tactac and Salacsac Pass in Malico, witnessed significant combat between the retreating Japanese Army and the pursuing Allied Forces. Brigadier General James Dalton II of the United States Army Forces in the Far East (USAFFE) lost his life in the battle of Balete Pass on May 16, 1945, which is now known as "Dalton Pass" in his memory. Similarly, a shrine was built in Salacsac Pass to honor the unknown soldiers who displayed heroism during the war.

On 9 November 1950, Executive Order No. 368, signed by President Elpidio Quirino, abolished the municipal district structure in government and attached Imugan to Aritao and Kayapa. The place gradually developed to become a progressive municipal district. Republic Act. No. 2179 was enacted on May 6, 1959, recreating the Municipal district of Imugan and changing its name to Santa Fe in honor of the Patron Saint San Jose de Santa Fe. By virtue of Executive Order No., 77 dated July 18, 1967 it was converted from a municipal district to a regular municipality by President Ferdinand E. Marcos.

Santa Fe currently has a boundary dispute with San Nicolas, Pangasinan, in which Santa Fe claims the territory of barangay Malico. The Nueva Vizcaya provincial board passed a resolution on September 21, 2022, urging San Nicolas officials to respect a memorandum of agreement between the National Mapping and Resource Information Authority (NAMRIA), Pangasinan, and Nueva Vizcaya about twenty years ago. On the same day, the Nueva Vizcaya provincial board held a special session in Barangay Malico and issued a resolution requesting San Nicolas officials to refrain from building infrastructure projects within the barangay's boundaries. Said resolution also instructed San Nicolas officials to "respect the boundary" of Santa Fe as well as "the rights of the Kalanguya tribe and their ancestral domain rights."

In July 2024, the Pangasinan provincial government has allocated ₱200 million (US$4.06 million) for projects and services in Malico. Governor Ramon Guico III asserted Malico's affiliation with Pangasinan, emphasizing the province's commitment to enhancing local infrastructure and services regardless of the territorial dispute. Nueva Vizcaya Governor Jose Gambito warns of potential legal repercussions for Pangasinan's investments in the area. He also said that the two government agreed to pay ₱600,000 (US$12,182.74) for every NAMRIA survey but Pangasinan allegedly did not fulfill its promises.
