The early coastal inhabitants believed to be adventurous settlers from neighboring provinces, originally settled northwest of Anahawan creek, where the palm-like Anahaw trees grew in abundance. It was earlier known as Kapirung. Anahawan was once a barrio of Hinundayan.
On January 1, 1931 the barrio was transformed into a separate municipality of Delgado, by Proclamation of the Governor-General, in honor of Congressman Jorge Delgado. Subsequently, Delgado by congressional act changed the name to Anahawan, preserving the legend that determined the natural indigenous origin of the town.
The place is bounded in the North by the Municipality of Hinundayan, in the south by the municipality of San Juan, in the East by the Surigao Strait and in the West by the Municipalities of San Juan and Hinunangan. There are 14 barangays comprising Municipality of Anahawan.
Anahawan comprises the barrios of Poblacion, Amagusan, Calinta-an, Canlabian, Capacuhan, Cogon, Kagingkingan, Lewing, Lo-ok, Mahalo, Mainit, Manigawong, San Vicente and Tagup-on.
