In Celtic mythology, Belatu-Cadros ("fair shining one" or "fair slayer"), also rendered Belatucadros or Belatucadrus, was a deity worshipped in northern Britain, particularly in Cumberland and Westmorland. He may be related to Belenus and Cernunnos, and was equated in the Roman period with Mars. He appears to have been worshipped by lower-ranked Roman soldiers as well as by Britons.
