Itbayat is a municipality located in the northernmost part of the Philippines, forming one of the three main islands of Batanes province in the Cagayan Valley region. Situated approximately 160 kilometers north of the Batan Island, Itbayat is the northernmost inhabited island of the Philippines and lies closest to Taiwan among Philippine territories. With a land area of approximately 83.13 square kilometers, Itbayat is characterized by its rugged limestone terrain, dramatic cliffs, and absence of sandy beaches, creating a unique landscape distinct from other islands in the archipelago. The municipality has a population of around 3,000 people according to recent census data, primarily engaged in agriculture, fishing, and livestock raising. Itbayat is divided into 5 barangays: Raele, San Rafael (Idiang), Santa Lucia (Kauhauhasan), Santa Maria (Marapuy), and Santa Rosa (Kaynatuan). The island's isolation has preserved its traditional Ivatan culture and stone houses, while its strategic location makes it an important outpost in the Luzon Strait.
