Ashildr (also known as Me) is a fictional character in the British science fiction television series Doctor Who, portrayed by Maisie Williams, who was introduced in the ninth series episode "The Girl Who Died".

Ashildr, daughter of Einarr (Ian Conningham), is introduced in "The Girl Who Died" (2015), where she is portrayed as a Viking puppet maker and storyteller. When the militaristic alien race the Mire raid her village, Ashildr declares war between the village and ten of the Mire. As part of a battle plan devised by the alien time traveller the Twelfth Doctor (Peter Capaldi), Ashildr uses the technology inside one of the Mire's helmets to create an illusion to scare the Mire into a retreat. In doing so, she dies of heart failure, having been "used... up like a battery" by being connected to the Mire's machine. The Doctor's companion, Clara Oswald (Jenna Coleman), a time-travelling school teacher from 21st century England, persuades the Doctor to save her. He implants Ashildr with Mire medical technology, bringing her back to life and making her functionally immortal, but he worries that there will be consequences.

In the following episode "The Woman Who Lived", the Doctor catches up with Ashildr in 1651 England after 800 years have passed for her. She has become a highwayman, adopting the new name of "Me". Having lived through many wars and suffered many losses, she plans to travel the galaxy with an alien Leonian called Leandro (Ariyon Bakare) after the Doctor helps her retrieve an amulet called the Eyes of Hades, not knowing this will create a portal using the death of rival highwayman Sam Swift the Quick (Rufus Hound). However, Leandro betrays Ashildr and, instead, summons a fleet of ships to attack Earth. Ashildr uses her spare piece of Mire medical technology to restore Sam's life and close the portal to Leandro's world. She promises the Doctor that she will watch over his companions on Earth, keeping them safe after they stop traveling with him. Shortly afterwards, he spots her in the background of a photo on Clara's mobile phone taken in the 21st century.
