Gallaecian or Northwestern Hispano-Celtic is an extinct Celtic language of the Hispano-Celtic group. It was spoken by the Gallaeci in the northwest of the Iberian Peninsula around the start of the 1st millennium. The region became the Roman province of Gallaecia, which is now divided between the Spanish regions of Galicia, western Asturias, the west of the Province of León, and the North Region in Portugal.

The Celtic languages are a group of related languages descended from Proto-Celtic. They form a branch of the Indo-European language family. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.
