Paul Stewart (born 29 October 1965 in Dumbarton, Scotland) is a former racing driver and the son of three-times Formula One World Champion Jackie Stewart.
Stewart competed in Formula Ford 2000 in 1988, the British Formula 3 Championship from 1989 to 1990 and in Formula 3000 from 1991 to 1993, both for his Paul Stewart Racing team. During the period, he was a teammate of Marco Apicella in 1991, David Coulthard in 1992 and Gil de Ferran in 1993. De Ferran won the first victory for the team in 1993. Thereafter, Stewart gave up his career as a driver and decided to concentrate on his role as team manager from 1994. The team won eight team championships in F3, 1992 to 1994, and 1996 to 2000.
In 1996, he and Jackie formed Stewart Grand Prix, which competed in Formula One from 1997 to 1999. At the end of 1999, Ford purchased the team, which became Jaguar Racing from 2000 and subsequently Red Bull Racing in 2005.
Stewart married his wife Victoria in 1993 and has four sons.
Paul's son Dylan worked as a summer intern at Red Bull Racing from 2010 to 2012.
In September 1999, Stewart was diganosed with Ulcerative colitis. A second colonoscopy in January 2000, did not detect cancerous cells. Further problems arose after Stewart was diganosed with bowel cancer in April 2000. Upon hearing the news, he stepped down as Chief Operating Officer for Jaguar Racing and subsequently travelled to the Mayo Clinic for treatment. A CAT scan showed no signs of cancer returning.
