Kamelion is a fictional character from the long-running British science fiction television series Doctor Who. A shape-changing android voiced by Gerald Flood in its default form, it is a companion of the Fifth Doctor and appears in the television series in two serials between 1983 and 1984.

When first encountered by the Doctor in England, Earth, 1215 A.D. The King's Demons, Kamelion is a tool of the renegade Time Lord known as the Master, who is forcing Kamelion to pose as King John. At the conclusion of the Master's previous encounter with the Doctor, he was trapped on the planet Xeriphas. When the Master returns, he has Kamelion with him, calling it a souvenir he had picked up from there. Although Kamelion is sentient to a degree, it is also extremely weak-willed, and therefore open to manipulation by any strong personalities around it. The Doctor frees Kamelion from the Master's grip, and it joins the Doctor in the TARDIS (much to Tegan's disapproval). Here it presumably spends all the intervening time between its two full appearances, out of sight and mind – notably no reference is even made to the character on-screen otherwise.

Kamelion eventually falls under the Master's influence again in the serial Planet of Fire. Kamelion finally begs the Doctor to destroy it, and the Doctor uses the Master's tissue compression eliminator (T.C.E) on him, shrinking him and destroying him, the last that is seen of Kamelion is the doll sized robot shell lying on the floor, with wires hanging out of its shoulder. The Kamelion robot's last appearance is as one of the images of his companions that comes to the Fifth Doctor during his regeneration scene in The Caves of Androzani.
