Sir John Young Stewart (born June 11, 1939 in Dumbartonshire, Scotland), better known as Jackie Stewart, is a three-time Formula One racing champion representing Great Britain. He holds an OBE.

Scottish-born Stewart seemed destined to become part of the world of motor carss. His father was the owner of a Jaguar garage, and his older brother was a gifted driver who raced for Jaguar.

In Formula One, Jackie Stewart began his career with the BRM team. He switched to Ken Tyrell's team where he drove Matra during the 1968 and 1969 seasons. After a dispute with Matra concerning the use of Ford engines, Stewart drove a March until Tyrell built its own cars.

Stewart became world champion in 1969 driving a Cosworth-powered Matra MS80. As of today he is the one and only driver to have won the championship driving a French car. He went on to win the Formula One world championship in 1971 and 1973 for Team Tyrell.

Stewart retired in 1973, subsequently becoming a consultant for the Ford Motor Company. At the same time, he became a spokesman for safer cars and circuits in Formula One. In 1997 Stewart returned to Formula One, with Stewart Grand Prix, as a team owner in partnership with his son, Paul, and the Ford Motor Company. The team was later bought by Ford and became Jaguar Racing in 2000. More recently, Robbie Williams honored him in his song Supreme. Stewart received a knighthood in 2001.
