Batanes (Ivatan: Probinsya nu Batanes; Ilocano: Probinsya ti Batanes; Filipino: Lalawigan ng Batanes) is an archipelago province in the Philippines situated in the Cagayan Valley region. It is the northernmost province in the country, and also the smallest, both in population and land area. Its capital is Basco located in the island of Batan.

The island group is located approximately 162 kilometres (101 mi) north of the Luzon mainland and about 190 kilometres (120 miles) south of Taiwan, separated from the Babuyan Islands of Cagayan Province by the Balintang Channel, and from Taiwan by the Bashi Channel.

The ancestors of today's Ivatans descended from Austronesians who migrated to the islands 4,000 years ago during the Neolithic period. They lived in fortified mountain areas called idjangs and drank sugar-cane wine, or palek. They also used gold as currency and produced a thriving agriculture-based industry. They were also seafarers and boat-builders.

In 1687, a crew of English freebooters headed by William Dampier came with a Dutch crew and named the islands in honour of their country's nobility. Itbayat was named "Orange Isle" after William of Orange, and Batan was named "Grafton Isle" after Henry FitzRoy, 1st Duke of Grafton. Sabtang Isle was named "Monmouth Isle" after James Scott, 1st Duke of Monmouth. Capt. Dampier stayed for less than three months, and did not claim the islands for the British crown.
