The Sixth Doctor is the name given to the sixth incarnation of the fictional character known as the Doctor, seen on screen in the long-running BBC television science-fiction series Doctor Who. He was portrayed by actor Colin Baker, and briefly by Sylvester McCoy during the Sixth Doctor's regeneration into the Seventh. This makes the Sixth Doctor one of only two incarnations of the Doctor to have been officially played by more than one actor, the other being the First Doctor.
