Busturialdea, also named Busturialde - Urdaibai is a comarca of the province of Biscay, in the Basque Country, Spain. It is the heir of "Busturia", one of the original merindades that used to compose the province of Biscay – this should not be confused with Busturia, a municipality located in this region.
