Klark Quinn (born 12 May 1982) is an Australian businessman and racing driver who last competed in the Bathurst 12 Hour for Quinn Racing Team MPC.
Quinn is the son of Tony Quinn, a British-born businessman and racing driver, founder of the Tony Quinn Foundation and the Quinn Group, who also owned the Australian GT Championship from mid-2011 to mid-2018. His brother Kent and son Ryder, with whom he raced at the 2026 Bathurst 12 Hour along with Tony, are also racing drivers.
In September of 2012, Quinn acquired Darrell Lea, nearly two months after it went into voluntary administration, and ran it until 2018 when Quadrant Private Equity took over the company. Six years later, Quinn purchased Sara Lee Australia in February of 2024, four months after the company went into voluntary administration.
Quinn began his racing career in 2001, by racing in Formula Ford Queensland and finishing third in points, as well as select appearances in the Australian Formula Ford Championship and the Class B of the Australian GT Production Car Championship. Another season in Formula Ford Queensland then followed, in which he finished third in points for the second year in a row, as well as racing part-time in Australian Formula Ford, and finishing second in the Bathurst 24 Hour in Class 9 for Novocastrian Motorsport.
In 2003, Quinn joined RT Motorsport to race in the second half of the Australian Carrera Cup Championship, taking a best result of third in race three at Surfers Paradise to end the year 13th in points. Towards the end of the year, Quinn returned to the Bathurst 24 Hour, finishing second in the B class for VIP Petfoods Racing. Remaining with the latter team for his sophomore season in the Australian Carrera Cup Championship, Quinn took a lone podium in race three at Bathurst, which helped him end the year fifth in the overall standings. Continuing in the series for 2005, Quinn took a best result of second four times, including in all three races at Surfers Paradise en route to seventh in points. During 2005, Quinn also finished second in the Gemini One Hour Race.
Two seasons in Australian Carrera Cup then ensued, in which Quinn finished 13th and 12th in points, as he took a best result of sixth in race two at Albert Park in 2006. During both years, Quinn also raced at the 24 Hours of Nürburgring, finishing sixth in the SP7 class in 2006, and seventh in class the following year. In 2008, Quinn began the year by winning the Dubai 24 Hour overall, before finishing second in the Bathurst 12 Hour overall and later racing in the 24 Hours of Nürburgring in the SP7 class. The following year, Quinn mainly raced in the Australian GT Championship, winning all five of his starts in the Challenge class, and later scoring two overall podiums in the final five races after being moved to the Championship class. During 2009, Quinn also raced in the 24 Hours of Nürburgring, finishing third in the SP7 class and ninth overall.
After finishing sixth in the 2010 Malaysia Merdeka Endurance Race, Quinn returned to the Australian GT Championship the following year, winning both races at Adelaide and race one at Townsville to secure runner-up honors in the overall standings. Returning for the 2012 season with a Porsche 911, Quinn won both races in Adelaide and Surfers Paradise and five other podiums to secure his maiden Australian GT title. Continuing in the series for 2013, Quinn won twice at Queensland and finished on the podium in the other nine races to seal his second consecutive Australian GT title by 104 points over his father Tony. During 2013, Quinn also returned to the Bathurst 12 Hour, finishing third overall alongside Matt Kingsley and Shane van Gisbergen, also for his father's VIP Petfoods Racing outfit.
Remaining with the family-owned team as they switched to McLaren machinery for 2014, Quinn finished fourth in the Bathurst 12 Hour, before returning to Australian GT for the rest of the year, taking a lone win at Townsville and four other podiums to end the year fourth in points. Returning for the 2015 season, Quinn scored a lone win at Adelaide with the MP4-12C, before switching to the 650S for the final four rounds, in which he won race one at Highlands to finish third in points. The day after the Australian GT season finale at the same venue, Quinn won the non-championship Highlands 101 alongside Van Gisbergen.
Continuing with the now-named Keltic Racing for the 2016 season, Quinn took a lone win at Townsville and four other podiums en route to his third Australian GT title, shortly before announcing his step back from full-time racing to focus on his family. Following that, Quinn raced in the Bathurst 12 Hour the following year alongside Tony Quinn, Grant Denyer and Andrew Waite. Nine years later, Quinn made a brief return to racing, competing in the Bathurst 12 Hour with his father Tony, his brother Kent and his son Ryder, as they finished eighth in class driving an Audi R8 LMS Evo II.
