Melanie "Mel" Bush is a fictional character played by Bonnie Langford in the long-running British science fiction television series Doctor Who. A computer programmer from the 20th century who is a companion of the Sixth and Seventh Doctors, she was a regular in the programme from 1986 to 1987 before Langford left the series. Langford reprised the role of Mel in the series following a cameo appearance in the 2022 serial "The Power of the Doctor," with the character's backstory and personality being fleshed out in greater depth than in her prior appearances.
Mel was unpopular in her original appearances due to appearing as a thinly characterized stereotype to audiences. Aspects of her portrayal, as well as reappearances of the character following her departure from the series, have been praised.
