Itbayat, officially the Municipality of Itbayat (Filipino: Bayan ng Itbayat; Ilocano: Ili ti Itbayat), is a municipality in the province of Batanes in the Cagayan Valley (Region II) of the Philippines. The population was 2,867 at the 2015 census. In the 2016 electoral roll, it had 1,720 registered voters. Itbayat is the country's northernmost municipality, located about 200 kilometers (120 mi) from the southernmost tip of Taiwan.
In addition to the main island of Itbayat which is the largest in Batanes, the municipality includes the rest of the province's northern islands, all small and mostly uninhabited. These islands are, from south to north: Diogo, Siayan, Maysanga, Mabudis, North, and Mavulis (also known as Y'ami), the northernmost island of the Philippine archipelago.
While the church and civil government were already established in Batan Island in 1783, it was only in 1855 that civil authority was officially established and the mission canonically founded in Itbayat. A mere settlement during the Spanish colonial period, it became a municipal district when the Americans organized the province in 1909. However, in 1935, it became a municipality.
