Dorothea "Dodo" Chaplet is a fictional character played by Jackie Lane in the long-running British science fiction television series Doctor Who. An Earth teenager from the year 1966, she was a companion of the First Doctor and a regular in the programme in its third season, from February to July 1966. Only three of the serials in which Dodo appeared as a regular are complete in the BBC archive (The Ark, The Gunfighters and The War Machines). Dodo's personality was an unsophisticated, bright and happy one.
Lane's contract was not extended beyond episode two of The War Machines. To replace her, two new characters, Polly (Anneke Wills) and Ben (Michael Craze), the new faces of Doctor Who in the "swinging" mid-1960s, became companions. Dodo appeared in six stories (19 episodes, of which 11 currently exist in the BBC Archives).
Dodo has appeared in several spin-off productions, including Big Finish audio dramas and novels, all without the involvement of Lane.
