John Simms.
His name in his childhood is Koschei,so thus,it is his real name.
For the 2011 series.The Doctor is being played by Matt Smith
John Smith is the only alias that he has ever used, to my knowledge.. I've watched the very first season and the new seasons (Christopher Eccleston, David Tennant, and now Matt Smith) But, in pretty much every episode in which he is asked that question, he simply calls himself "The Doctor", just as he refers to the Master simply as "The Master" and nothing more. This leads me to believe that he has no "real name," as you put it
The actor who plays the 10th Doctor's real name is David Tennant. However, if you mean what is the name of the Doctor himself, nobody knows his actual name.
Doctor Roger Prynne was his REAL NAME and Doctor Chillingworth was the false name he used.
his real name is lavender and his sure name is trogg
the name of the tenth doctor is david tennant .however this xmas in 2009 he will resign as the doctor and will be strongly missed and i myself am not watchin any other doctor who episodes that do not have david in them.the 11th doctor is going to be Matt smith.
Doctor who real name is ........ Paul maker
That IS his real name ! He was also known by the name 'Master Mahashay'.
Master Chief Petty Officer John-117, his name is John
Master P's birth name is Percy Robert Miller.
