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, which should not be confused with Busturia, which is a municipality located in this region. Busturialdea is a diminished portion of the same original subregion and has two capital cities; Bermeo and Gernika-Lumo. It is one of the seven comarcas that compose the province of Biscay.
Busturialdea was historically the core of Biscay: the capitals of the province, Bermeo and Gernika, were located in it; the village of Mundaka, also belonging to this region, had the privilege of speaking always first in the sessions of its parliament and for some time, the harbour of Bermeo was the main portuary facility, until Bilbao was founded in 1300.
Busturialdea and its lush estuary was also important in prehistory. Particularly significative is its site of Santimamiñe cave, that yielded a full sequence of human habitation from Neanderthals to the Iron Age, and beautiful Magdalenian cave paintings.
