Stefan James Wilson (born 20 September 1989 in Sheffield, UK) is a British racing driver. He is the younger brother of the late Formula One and IndyCar Series driver Justin Wilson. He is also the winner of the 2007 McLaren Autosport BRDC Award for promising young British drivers.

After a long karting career as a child, Stefan stepped up to open-wheel racing in November 2006, competing in the Formula Palmer Audi Autumn Trophy at Snetterton and Brands Hatch. Stefan gradually improved throughout his first six car races and finished the six-race mini-series in ninth place, also ending as top rookie. He picked up three top-six finishes and set the fastest lap in the final round at Brands Hatch.

Stefan competed in the 2007 Formula Palmer Audi Championship, the tenth anniversary of the series, and also the tenth anniversary of when his brother Justin won the first FPA title. He finished second in the championship after a great final round at Croft, where he scored two podiums after his worst qualifying of the season, only starting seventh and ninth for the two races. Stefan overtook a total of eleven cars. He also closed the final gap between him and more experienced driver Tim Bridgman to just 28 points.

He scored 4 wins throughout the season; the first came in round 4 of the championship at the Brands Hatch Grand Prix circuit in front of nearly 50,000 spectators. The second half of Wilson's championship was more successful as he scored four pole positions and three of his four wins. Wilson ended the championship in second place, with a tally of four wins, nine podiums, four pole positions, five fastest laps, and two lap records.

At the end of the season he won the McLaren Autosport BRDC Award for young British drivers. Part of the award was a prize drive in a McLaren Formula One car, which took place on the Silverstone National Circuit on 13 November 2009.

In 2008, Wilson competed in the British Formula 3 Championship National Class in 2008 with Fluid Motorsport and captured four class wins on his way to fourth in the National Class points standings.

Wilson signed to race a partial schedule in Firestone Indy Lights in 2009 for First Motorsports with cars prepared by Walker Racing that included six road and street courses. He qualified third at Long Beach but was sidelined by a mechanical problem towards the finish. His best finish was fourth in the wet/dry race at Toronto. In 2010 returned to the series to race for Bryan Herta Autosport. Wilson finished eleventh in points despite missing one race due to funding issues and another due to a damaged racecar. He had a career-best finish of third in the season opener at St. Pete and ran the fastest race lap in Toronto.

In 2011 he returned to Indy Lights full-time with Andretti Autosport. He captured one pole, two wins, and finished on the podium three more times to finish third in the championship. Despite Wilson's 2011 success, he was out of racing until the 2012 Indy Lights season finale at Auto Club Speedway where he drove for Fan Force United and finished sixth.
