Colin Teague (born 1970) has directed a number of Doctor Who universe stories. He is one of the few directors to work on all three BBC Wales series.
He became widely known amongst BBC Wales personnel as "Tumblin' Teague", following an incident during the filming of The Sound of Drums, in which he fell and required brief hospitalization. David Tennant first revealed the nickname to the public in commentaries for series 3 episodes.
