Ryan Briscoe (born 24 September 1981 in Sydney) is an Australian auto racing driver who has raced open wheel and sports cars in Europe and America.

Like many auto racing drivers, he started his career in karting, first racing in 1993. After winning Australian, North American and Italian championships, he moved to Formula Renault in 2000. He won the Italian Championship in 2001 (winning 5 races) and finished 4th running a limited schedule in the Eurocup (with 2 wins in 6 races). In 2002, he became test driver for the Toyota Formula One constructor. He started that year racing in the Formula 3000 series, but struggled and left his ride after 7 races. He finished the year in the German Formula 3 series, taking 3 podiums in the last 6 rounds. He won the Formula Three Euroseries in 2003 (winning 8 races in the process). He became the Toyota F1 team's 'third' driver (ie, drove the team's test car on Fridays at Grands Prix) for the last third of the 2004 season, after previous third driver Ricardo Zonta was called up to replace Cristiano Da Matta.

There were rumors that Briscoe was set to race for the Jordan Grand Prix F1 team in 2005, due to the team's acquisition of Toyota power. Instead, Briscoe raced for Target Chip Ganassi Racing in the Indy Racing League, including a 10th place finish in the Indianapolis 500. He also made his Rolex Grand-Am debute with Ganassi at the 24 Hours of Daytona. He took pole position at Sears Point, but struggled on the ovals and was involved in several crashes.
