Ivor Léon John Bueb (/ˈbwɛb/;[1] 6 June 1923 – 1 August 1959) was a British professional sports car racing and Formula One driver from England.

With the death of Archie Scott Brown at Spa in May 1958, Brian Lister hired Bueb to fill the now-vacant Lister-Jaguar driver's seat.

Bueb did an admirable job, scoring several first places at tracks such as Crystal Palace and Goodwood during the 1958 and 1959 sports car campaigns.

Bueb is perhaps best known for sharing the winning works Jaguar D-type with Mike Hawthorn in the 1955 24 Hours of Le Mans which was marred by an accident in which 82 spectators were killed; a success he repeated with Ron Flockhart in the ex-works Ecurie Ecosse car in 1957.

[2] It was Ivor Bueb's death, in conjunction with Archie Scott Brown's demise, that finally led Brian Lister to shut down his very successful sports car racing effort.
