Lucien Bianchi (10 November 1934 – 30 March 1969), born Luciano Bianchi, was an Italian-Belgian racing driver who raced for the Cooper, ENB, UDT Laystall and Scuderia Centro Sud teams in Formula One. He entered a total of 19 Formula One World Championship races, scoring six points and had a best finish of third at the 1968 Monaco Grand Prix.
He died in a testing crash in preparation for the 1969 24 Hours of Le Mans.
Bianchi was born in Milan, Italy, but moved to Belgium in 1946 when he was still a child, with his father who was a race mechanic working, before the Second World War, in the Alfa Romeo competition department. His grandnephew, Jules Bianchi, who made his Formula One debut with the Marussia team for the 2013 season competing under the French flag, also died as a result of injuries sustained in a racing accident.
Lucien Bianchi's first race event was at the Alpine Rally in 1951. He won the 1957, 1958 and 1959 Tour de France as well as the Paris 1000 sports car race in the latter two years.
He entered Formula One in 1959, although only with sporadic appearances at first. He drove various cars under the banner of the ENB team, including a Cooper T51, a Lotus 18 and an Emeryson. After a couple of races for the UDT Laystall team in 1961, driving another Lotus, he returned to ENB for whom he drove their ENB-Maserati. He finally secured a more regular drive in Formula One in 1968, with the Cooper-BRM team, although success was elusive despite a bright start. Bianchi managed his best Formula One performance, finishing third at the 1968 Monaco Grand Prix, in his first race for Cooper.
Bianchi also raced touring cars, sports cars and rally cars, being successful in all disciplines, his biggest victories coming in the 1968 24 Hours of Le Mans, behind the wheel of a Ford GT40 with Pedro Rodríguez and at Sebring in 1962 with Jo Bonnier. He was also leading the 1968 London-Sydney Marathon when his Citroën DS collided with a non-competing car.
He was killed when his Alfa Romeo T33 spun into a telegraph pole during Le Mans testing in 1969.
At Circuit Zolder, the fourth turn of the circuit, entering the back stretch, is named LucienBianchiBocht in his memory.
