"The Eaters of Light" is the tenth episode of the tenth series of the British science fiction television series Doctor Who. It was written by Rona Munro and broadcast on 17 June 2017 on BBC One. Munro previously wrote Survival, the final serial of the original run of Doctor Who, making her the only writer to date to have worked on the classic and revived eras of the show. The episode received generally positive reviews from television critics.

The Doctor (Peter Capaldi) takes Bill (Pearl Mackie) and Nardole (Matt Lucas) to second-century Scotland to settle their different theories about what happened to the ninth legion of the Roman army that vanished. When they arrive, however, they find an alien menace from another dimension that may be the reason behind the vanishing, but is a far greater threat than any army.
