The Varduli are a pre-Roman tribe settled in the north of the Iberian Peninsula, in what today is the western region of the Basque Country.

Their historical territory corresponds with the current Basque area; however, it is not entirely clear whether the Varduli were actually Aquitanians, related to the Vascones, or Celticized tribes, related to Cantabri or Celtiberians which later underwent Basquisation. It seems probable the group shared the proto-Basque cultural-ethnic identity of the people of this region.
