The town derived its name from the nearby Angaranan Creek, a notable geographical feature of the area. The creek serves a significant role in the early development and identity of the settlement. The creek's presence influenced the local ecosystem by providing a source of potable water for both people and livestock. It also likely served as a critical landmark for the town's first inhabitants. The decision to name the town after Angaranan Creek reflects the community's connection to the natural landscape and highlights the importance of the creek in the town's history and daily life.
The town of Angadanan was initially founded in the mid-18th century as a settlement in present-day Nueva Vizcaya, between the towns of Bagabag and Bayombong. In 1776, the Spaniards decided to move the settlement further north in present-day Isabela province along the Ganano river, a tributary of the Cagayan River. In the 19th century, the Spaniards decided to move the town again six kilometers further east to its present location along the Cagayan River to facilitate better transportation links and to secure the town from repeated raids by the Igorots and Gaddangs. The second site was subsequently known as Angadanan Viejo (Old Angadanan) and the current site called Angadanan Nuevo (New Angadanan) until the former was converted into a separate municipality in 1949 named Alicia and the Nuevo was dropped from its official name.2
Angadanan is 58.56 kilometres (36.39 mi) from the provincial capital Ilagan, and 388.54 kilometres (241.43 mi) from the capital Manila.
