Adam Norman Carroll (born 26 October 1982) is a British professional racing driver. He last raced in the 2016–17 Formula E season for Jaguar Racing. He has also raced for Team Ireland in A1 Grand Prix, winning the series in 2009.

Carroll, who was born in Portadown, Northern Ireland, started his career in 1993 competing in karting events. He continued in karting until 1998. After winning the Elf LA FILIERE SCHOLARSHIP in 1999 he moved on to British Formula Ford, winning the Winter Series and taking 3rd in the festival. He raced in the British Formula Ford competition in 2001, before successfully making the move to British Formula 3 B-Class in 2002 with the Sweeney team. Despite driving year-old cars, Carroll was always an outright front runner and he dominated the class winning the title with a record points tally.

In 2003, Carroll moved up to Championship Class British Formula 3, but due to lack of finance, he had little stability and finished the year having driven with three different teams (eight podiums in a row with Menu), before competing in part of the Formula Three Euroseries season, where despite being new to both team, series, track and tyres, he finished in the points in his first race. He also partnered and outperformed future Formula One driver Nico Rosberg in an end of season event in South Korea. He continued in Formula Three throughout 2004, finishing as runner up to Nelson Piquet Jr. before joining the 2005 GP2 Series, replacing Hayanari Shimoda at the Super Nova Racing team just before the start of the season.

Although Carroll's pre-season preparation for GP2 left him at a disadvantage to all the other drivers due to the lateness of his race deal and consequent lack of testing with his new team, he was immediately competitive, briefly challenging for the championship before slipping back as the season progressed due to reliability setbacks and on-track incidents.

Despite continually having trouble raising a budget for his racing, he has still managed to outperform drivers who have had funding readily available to them, including 2005 team-mate, and ex F1 driver, Giorgio Pantano. His undoubted talent caught the eye of Formula One and in 2005 he was signed as a test driver for Formula One team BAR-Honda. For the 2006 GP2 season he surprised many in choosing to join the Racing Engineering team when his previous team had a better chance of picking up the title. It soon became clear that due to Carroll's continued lack of sponsorship, the Racing Engineering deal saved him from having to drop out of top line motorsport altogether. He has since removed himself from the Honda driver program sensing a lack of opportunity as Button and Barrichello would be hard to replace.

The only real high point of the 2006 season was a pole position, third place and second place combo at Silverstone. It was clear throughout the season, however, that Carroll's team was not as strong as the majority of the other teams in the series. This was highlighted many times due to car failures that cost him many points throughout the year. As well as this, the car was distinctly slower and he also had trouble with other drivers hitting him from behind. This coupled with a driver error while leading race two in Hungary cost Carroll a lot of points that, should he have gained them, he would have been in contention for at least third in the championship. As it was though, Carroll's 33 points was enough to give him eighth place (equal points with seventh-placed Gianmaria Bruni with Bruni ahead having scored more wins). Carroll scored all of his team's points, outscoring his old team Super Nova Racing.

For the start of the 2007 season, Carroll was driving a two-year-old Audi A4 in the German DTM series for the Futurecom TME team. On 26 June it was announced that he would replace Antônio Pizzonia in the FMS GP2 team for the event supporting the French Grand Prix. Carroll won at the Silverstone round of the GP2 series and scored four other points to take a total of thirteen in one weekend, only his second back in GP2, in a car that had only scored one point beforehand. It was announced on 13 July that he had left the DTM due to sponsorship problems, and concentrated on GP2 for the rest of 2007. Carroll also went on to claim victory in the first race at the Hungaroring, despite starting sixth and changing all four tires during his mandatory pit stop. The season did not end so well for Carroll, as he scored only 2 points in the last three races despite being in contention for much more. However, he did finish in seventh place, ahead of many drivers who, unlike Carroll, had completed the entire season. During this time, Carroll had tested the A1GP car for Ireland, which led to him being signed to race in A1GP. In his first start, he scored Ireland's biggest points haul in the history of A1GP by scored a podium in his first race and despite starting eighteenth on the grid due to being blocked in qualifying, sixth in the feature race. Later in the season, he won the Mexico City feature race, Ireland's first win in A1GP. He also finished on the podium at Brands Hatch, en route to helping Team Ireland finish sixth overall in the championship.

Carroll began the 2008 GP2 Series season without a drive, but when Adrián Vallés was dropped by FMS International after the first round of the season, he took part in four races for his old team. He was then replaced by Marko Asmer.
