Cagdianao, officially the Municipality of Cagdianao (Surigaonon: Lungsod nan Cagdianao; ceb|Lungsod sa Cagdianao; tl|Bayan ng Cagdianao), is a 3rd class municipality in the province of Dinagat Islands, Philippines. According to the 2020 census, it has a population of 18,350 people.
Cagdianao is derived from kagdianao, an alternate form of kaagdao-an, meaning "place where mangroves grow", from agdao, a local name for a species of mangrove.[1]
The town became a part of the province of Dinagat Islands in December 2006, when the province was created from Surigao del Norte by Republic Act No. 9355. However, in February 2010, the Supreme Court ruled that the law was unconstitutional, as the necessary requirements for provincial land area and population were not met. The town reverted to Surigao del Norte.[2] On October 24, 2012, however, the Supreme Court reversed its ruling from the previous year, and upheld the constitutionality of RA 9355 and the creation of Dinagat Islands as a province.[3]
Cagdianao is politically subdivided into 14 barangays. Each barangay consists of puroks while some have sitios.
