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.
Wilson 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. Wilson overtook a total of eleven cars. He also closed the final gap between him and more experienced driver Tim Bridgman to just 28 points.
Wilson 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, Wilson 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.
In 2011, Wilson 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.
On 26 April 2016, it was announced that Wilson would be driving for KV Racing Technology at the 100th Running of the Indianapolis 500. Wilson would be driving the No. 25 Driven2SaveLives Chevy. He chose No. 25 in honor of his late brother Justin, who drove the No. 25 car when he received his fatal injuries during an incident at the 2015 ABC Supply 500.
A fuel gamble put Wilson in the lead late in the 2018 Indianapolis 500, but he had to pit for fuel with four laps to go, and Will Power won the race.
Wilson finished in last place at the 2021 Indianapolis 500 due to a crash upon entering the pit lane early in the race.
During the 2023 Indianapolis 500, Wilson originally qualified for the race with a starting position of 25th on the grid. However, during the last practice session, Wilson suffered a back injury when he crashed after Katherine Legge ran into the back of him. As a result, Wilson was forced to withdraw from the event and was replaced by Graham Rahal, who initially failed to qualify after being bumped from the field.
