The Jaguar XKSS is a road-going version of the Jaguar D-Type racing car produced in England in 1957 and sold as a roadster. Only 16 examples were sold in that year, with a further 9 chassis destroyed in a factory fire before they could be completed.

After the company withdrew from competition at the end of the 1956 season, a few completed and partially completed D-Type models remained. In an attempt to recoup at least some of the investment, several vehicles were converted to road specification. The car was powered by a 3.4-litre I6 engine mated to a 4-speed manual gearbox. In 2016, the company announced that it would complete the original order of 25 cars by hand-building the remaining nine examples.
