Castellan, in the context of the BBC television series Doctor Who, is a title adopted by one or more high-ranking Time Lords, such as Castellan Spandrell,Castellan Kelner and the unnamed Castellan, who is/are member/s of the High Council of Gallifrey and is/are in charge of the security of the Citadel. The Chancellory Guard reports to a/the Castellan. It is unclear whether the times in office of the Castellans depicted in the series overlap or not.

The Castellan, played by Paul Jerricho, is a fictional character from Doctor Who. He is a member of the High Council of Gallifrey and is a Time Lord. He appears in two Doctor Who stories, Arc of Infinity and The Five Doctors.

In Arc of Infinity, the Castellan investigates a serious security breach on Gallifrey. He suspects the Doctor, who is sentenced to death. After the Doctor's termination fails, the Castellan is led to think that the Doctor is in league with President Borusa. Locating Borusa, the Castellan finds the Doctor with him. The Castellan pulls a gun on the Doctor intending finally to execute him. However, the real traitor Councillor Hedin jumps in front of the Doctor taking the Castellan's shot and dying. Confused, the Castellan looks on as Omega seizes control of the Matrix. As the Doctor attempts to thwart Omega, the Castellan develops a new respect for his former suspect.

In The Five Doctors, the Castellan is seen to have voted with the rest of the inner council to overrule Borusa and summon the Master to rescue the Doctor from the Death Zone. The Castellan supplies the Master with a recall device that will emit a signal so that he can be transmatted back to the Capitol when he has something to report. Having refused to believe the Master is trying to help him, the Doctor takes the Master's recall device, dropped during a Cyberman ambush, and is transported by the Castellan, (who thinks he is retrieving the Master), to the Capitol where he learns that the Master was telling the truth. The Castellan had hoped the Doctor would know who was controlling the Death Zone but the Doctor does not although he suspects a high-ranking Time Lord of being responsible.
