Surigaonon is a Philippine language spoken by Surigaonon people in the province of Surigao del Norte, Dinagat Islands, Surigao del Sur, and some portions of Agusan del Norte especially the towns near the Mainit Lake, Agusan del Sur and Davao Oriental. Though it seems related to Cebuano it was due mainly to the influx of many Cebuanos in the region and some Cebuano words were loaned, although most Cebuano speakers can hardly understand Surigaonon speakers except for Cebuanos who has been living in the region for years.
