Jonathon Webb (born 10 December 1983) is an Australian motor racing driver, currently competing in the V8 Supercar Championship Series.
Webb is a former BMX bicycle racing champion. He first came to national attention by racing Porsches out of the family run Tekno Autosports team which had previously operated racing cars for his father Steve. Webb spent several years racing in the Australian Carrera Cup Championship finishing eighth in the inaugural 2003 series. Webb's best run in the Carrera Cup was third place in the 2005 series. The following year Webb made his debut in the V8 Supercars as an endurance race co-driver for Marcus Marshall in the Paul Cruickshank Racing prepared Ford Falcon.
For 2007 Webb focused full-time on V8 Supercar racing, taking the family Tekno Autosports team into the Fujitsu V8 Supercar Series with Stone Brothers Racing preparing a Ford Falcon for them. Webb finished fourth in his first season, improving to third in 2008.
In 2009 Webb moved to the MW Motorsport team, a professional Fujitsu Series team. Webb won six out of the seven last races in the season in an irresistable charge to the championship crown. Webb began his association with Dick Johnson Racing in 2009, taking part in his fourth season as an endurance race co-driver in the V8 Supercar Championship Series. Webb continued this involvement into 2010, having secured a former Britek Motorsport Racing Entitlement Contract for the Tekno Autosports team. Tekno formed a technical alliance with Dick Johnson Racing with Webb's car to effectively become the team's third car, although ownership of the franchise will remain with the Webb family. Tekno secured car number 19 from the Sieders Racing Team to use for 2010, to match DJR's existing cars, 17 (Steven Johnson) and 18 (James Courtney). Mother Energy Drink became major sponsor of the #19 Ford partway into the 2010 season. Webb won his first V8 Supercar race on the Saturday at the 2010 Sydney 500 in wet conditions.
