Catanduanes (Filipino:Katandwanes) is an island province of the Philippines located in the Bicol Region in Luzon. Its capital is Virac and the province lies to the east of Camarines Sur across Maqueda Channel. As of 2007, the population of the province is 232,757 people.

"Isla de Cobos" was Catanduanes' first adopted name. It was earned as such during the early part of 1573 when Spanish conquistadores came upon several tribes living in the thatched huts called cobos.

Catanduanes, is a hispanized term derived from the word tandu, a native beetle and the samdong tree, which were both found in abundance throughout the island. Common reference to "katanduan" or "kasamdongan", meaning a place where the tandu or the samdong tree thrives in abundance, led to the coining of the word Catanduanes.

The scions of the then Bornean Datus who had moved on the island of Panay and then, spread out throughout the archipelago were the first settlers to have set foot in Catanduanes. The island was not spared from the adventurous raids of the Moros who came from the island of Mindanao. Because of these destructive raids, many records of the past were destroyed and lost.
