Long before its formal creation as an independent province, Quirino was the forest region of the province of Nueva Vizcaya, inhabited by tribal groups known as the Negritos. They roamed the hinterlands and built their huts at the heart of the jungle.
On June 18, 1966, Republic Act 4734 was enacted, constituting the municipalities of Diffun, Saguday, Aglipay, and Maddela (all of Nueva Vizcaya province) into a new sub-province to be known as "Quirino", named after the late Philippine president Elpidio Quirino.
On June 21, 1969, Republic Act 5554 was enacted, amending RA 4734 and creating the municipality of Cabarroguis (now the provincial capital town), which was taken from portions of Diffun, Saguday, and Aglipay.
Republic Act 6394, authored by former Congressman Leonardo B. Perez, was passed on September 10, 1971 further amending RA 5554 and separating the sub-province of Quirino from its mother province, Nueva Vizcaya, constituting it into a regular province. 
The province of Quirino was formally established on February 10, 1972 upon the assumption to office of the first elected provincial and municipal officials headed by Dionisio A. Sarandi as Provincial Governor.
Quirino lies in the southeastern portion of Cagayan Valley. It is situated within the upper portion of the Cagayan River basin and bounded by Isabela on the north, Aurora on the east and southeast, and Nueva Vizcaya on the west and southwest.
The Sierra Madre mountain range provides a natural barrier on the eastern and southern border of the province and the Mamparang Range on the western part. The province is generally mountainous, with about 80 percent of the total land area covered by mountains and highlands. A large portion of the province lies within the Quirino Protected Landscape.
The province has a mean annual temperature of 33.6 °C (92.5 °F). May is generally the warmest month and the wettest months are March to August, with the rest of the year being neither too dry nor too wet. Heavy, sustained rainfall occurs from September to November.
