Dinalungan, officially the Municipality of Dinalungan (Tagalog/Kasiguranin: Bayan ng Dinalungan; Ilocano : Ili ti Dinalungan), is a municipality in the province of Aurora, Philippines. According to the 2024 census, it has a population of 12,552 people, making it the least populated municipality in the province. ^[5]

Two protected areas, the Talaytay Protected Landscape and the Simbahan-Talagas Protected Landscape, are located in the municipality.

History

Dinalungan traces its roots as a barrio that was part of Casiguran, ^[6] which experienced numerous provincial transfers since the Spanish colonial period. The area was annexed by Nueva Ecija in 1818 and was later made part of Nueva Vizcaya in 1839. ^[7] It then belonged to the El Príncipe District of Nueva Ecija beginning in 1856. ^[8] During the American occupation, Casiguran became part of Tayabas (now Quezon) in 1902, briefly merging with Baler from 1906 to 1907. ^{[9] [10] [11]} Though it was transferred back to Nueva Vizcaya in 1918, Casiguran was ultimately returned to Tayabas in 1946.

On June 18, 1966, barrios Simbahan and Dinalongan and sitios Abuleg, Bungo, Balante, and Nipoo were separated from Casiguran to form the new municipal district of Dinalungan (Dinalongan), by virtue of Republic Act No. 4757. Barrio Dinalongan was designated as the seat of municipal government. The first set of local officials were elected in the following 1969 elections. ^[12] At the time of its creation, Dinalungan was part of the province of Quezon under its sub-province of Aurora until the latter was converted into a province on August 13, 1979. ^[13]
