The Stig is the name given to the racing driver character on the BBC Television show Top Gear (Top Gear (2002 TV series)). In the show he is cast as a mysterious "Tame Racing Driver". He is credited alongside Jeremy Clarkson, Richard Hammond, and James May as a presenter in the end credits.

The Stigs primary functions on the show are to post Power Lap (Power Laps) times in various cars around the Top Gear Test Track (Top Gear Test Track) in Dunsfold Park (Dunsfold#Dunsfold Park), and to train each weeks celebrity guest in setting a lap time in the "Star in a Reasonably-Priced Car" feature on the show. In addition, The Stig carries out other driving and personal appearance duties when the need arises. The Stig has also appeared on some of Clarksons motoring specials, such as Heaven and Hell, Thriller, and Duel.

The identity of the character is a closely guarded secret. The BBC has officially stated that it does not "comment on speculation as to who or what the Stig is." Efforts to conceal the real identity have included intentional hoaxes, such as having seven-time Formula One World Champion (List of Formula One World Drivers Champions) driver Michael Schumacher dress up and pretend to be the character.
