Geoffrey John Brabham (born 20 March 1952) is an Australian racing driver. Brabham spent the majority of his racing career in the United States.
Brabham also won the 1993 24 Hours of Le Mans driving one of the factory Peugeot 905 alongside French drivers Éric Hélary and Christophe Bouchut. His younger brother David Brabham had won the GT class in the race driving a Jaguar XJ220 for Tom Walkinshaw Racing, but the team was later disqualified for technical infringements. Geoff Brabham became just the third Australian driver to win Le Mans after Bernard Rubin (1928) and Vern Schuppan in 1983. Brabham would also go on to win Le Mans in 2009, also driving for the factory Peugeot team.
Brabham dabbled in V8 Supercar drives in his native Australia throughout his career. He is still one of the few drivers to win his first race, Sandown 500 in 1993. He started eleven races for one victory.
Married to Roseina Brabham, a multi-time jet-ski champion, Brabham has retired from competition himself to focus on his son Matthew Brabham's racing career. After a successful karting career, Matthew moved into international open-wheel racing and the Road to Indy ladder; he is also a three-time Stadium Super Trucks champion.
