Bill Potts is a fictional character created by Steven Moffat and portrayed by Pearl Mackie in the long-running British science fiction television series Doctor Who. In the show's tenth series, starting with the first episode, Bill served as a companion of the twelfth incarnation of the alien time traveller known as the Doctor (portrayed by Peter Capaldi).

Bill Potts is introduced in the tenth series premiere, "The Pilot". In their first encounter, Bill is discovered by the Doctor, who is hiding out as a university professor. Noticing her untapped potential, he offers to privately tutor her. However, when Bill's love interest Heather (Stephanie Hyam) is turned into a water creature that can travel anywhere in space and time, the Doctor reveals to Bill his alien nature and takes her on as his travelling companion, much to the chagrin of his assistant Nardole (Matt Lucas), who urges the Doctor to stay in Bristol and keep watch over a strange safe below the university.

In subsequent episodes, Bill learns about the Doctor's Time Lord nature and the rules of time travel, averting alien invasions and ending conflicts on faraway planets and deep space, growing closer to the Doctor all the while. In the series finale, "World Enough and Time" / "The Doctor Falls", Bill is shot through the heart after the Doctor's crew reacts to an alien distress call aboard a spaceship, and is carried away by menacing scientists to a lower deck where time moves much more rapidly. Bill's life is saved, but ten years pass before the Doctor is able to reach her, during which time she is converted into a Cyberman. Though Cybermen are normally emotionless and hellbent on converting humans to their ranks, Bill retains her humanity and sense of identity as a result of particular experiences she has had travelling with the Doctor. When the Cybermen are defeated, Bill is entirely alone: the Doctor appears dead, Nardole has taken human refugees to safety, and she is a horrific monster. She is rescued, however, by Heather, who transforms her into a creature like herself and offers Bill the choice of travelling space and time together, or being returned to her life on Earth as a normal, living human again. Bill returns the Doctor's body to the TARDIS, and bids him a sad farewell, before taking off with Heather to explore the universe.
