List of Doctor Who supporting characters

Over the course of its many years on television, the long-running British science fiction television series Doctor Who has not only seen changes in the actors to play the Doctor, but in the supporting cast as well. This is not an attempt to make a comprehensive list of all supporting characters or alien races in Doctor Who, but merely the most significant.

Companions
The Doctor is usually accompanied in his travels by one to three companions (sometimes called assistants). These characters provide a surrogate with whom the audience can identify, and further the story by asking questions and getting into trouble. The Doctor regularly gains new companions and loses old ones; sometimes they return home, or find new causes on worlds they have visited. Some companions (notably Katarina, Sara Kingdom and Adric) have died during the course of the series.

There is some disagreement over the definition of a companion. Most companions travel in the TARDIS with the Doctor for more than one adventure, although there are exceptions: Liz Shaw never traveled in the TARDIS in the television series, and Sara Kingdom died in the same adventure in which she made her debut. Fans also disagree on whether Brigadier Lethbridge-Stewart and other UNIT staff, who sometimes filled the companion's dramatic role during the Third Doctor's exile on Earth, should be counted as companions. Sometimes a guest character will take a role in the story similar to that of a companion: one recent example is Lynda in Bad Wolf and The Parting of the Ways.

The new series (2005–) has slightly altered the significance of the companion status, partly due to a strong focus on the character of Rose Tyler and characters connected to her. For example, although Adam Mitchell was a companion by the standard definition, he appeared in only two episodes and was arguably a less significant part of the 2005 series than Rose's sometime boyfriend Mickey Smith, who was not technically a companion during the 2005 series, but appeared in five episodes (or six, including a brief appearance as a child in Father's Day).
