The Scot played the time-travelling Doctor between 2005 and 2010 and has topped a poll by RadioTimes.com to find viewers' most beloved incarnation of the cult Tv figure.
He gained 56 per cent of the vote, followed by current Time Lord Matt Smith, who will be stepping down later this year (13) to make way for the new Doctor, Peter Capaldi.
In third was Tom Baker, who played the character from 1974 to 1981, fourth went to Christopher Eccleston, who only lasted one run when the show was rebooted in 2005. The top five was rounded out by 1960s Doctor Who Patrick Troughton.
Meanwhile Tennant's sidekick, Billie Piper, was named as best companion, followed by Elisabeth Sladen and Catherine Tate.
A 50th anniversary special will air in the U.K. later this month (Nov13).
