Cabadbaran is the capital city in the province of Agusan del Norte, Philippines. It has a population of 69,241 according to the NSO Census of 2010. Founded in 1894, the city rose from its Spanish period beginnings to become the premier town of Agusan del Norte. Its rich cultural heritage is evident in its preserved colonial period houses and its archaeological collections. Following its recent declaration as a city, it is also the officially designated capital of the province per Republic Act 8811.

Cabadbaran is politically subdivided into 31 barangays.

CABADBARAN, as a community, is very old, so old that one could trace its existence back to 1200A.D. Traces of the existence of 12th century villages could be found along ancient waterways dissecting the territory now called Cabadbaran. Along the old creeks of Caasinan, Cambuayon and Capudlusan, pre-Spanish Cabadbaranons once lived, worked and died during the 9th -12th centuries, contemporaneous with the old archaeological sites in Butuan City. Artifacts from these pre-Spanish villages could be found today at the Cabadbaran City Artifacts Gallery now temporarily housed at the City Library.
