Northwestern Hispano-Celtic, or less frequently Gallaecian, is an extinct language of the Celtic family and it was one of the Hispano-Celtic languages. It was spoken at the beginning of the first millennium CE in the Northwest of the Iberian Peninsula, in an area lying between the west and north Atlantic coasts and a line running north-south and linking Oviedo and Mérida, the former Gallaecia, including the areas of modern-day Galicia, western Asturias and northern Portugal.
