The Jaguar XK120 is a sports car manufactured by Jaguar between 1948 and 1954. It was Jaguar's first sports car since the SS 100, which ceased production in 1940.

Jaguar XK120 Jaguar XK120 open 2-seater Overview Manufacturer Jaguar Cars Production 1948–1954 12,055 made Assembly Holbrook Lane, Coventry, England, United Kingdom Browns Lane, Coventry, England, United Kingdom.

The XK120 was ultimately available in three versions or body styles, first as an open 2-seater described in the US market as a roadster (OTS) then as a fixed head coupé (FHC) from 1951 and finally as a drophead coupé (DHC) from 1953, all two-seaters and available with Left (LHD) or Right Hand Drive (RHD). However, certain Special Equipment roadster and fixed head coupe cars were produced between 1948 and 1949 denoted by an 'S' preceding the chassis number. These Special Equipment cars were sold as an early production build for enthusiasts.[citation needed] A smaller-engined version with a 2-litre 4 cylinder engine, designated the XK100, intended for the UK market was cancelled prior to production. On 30 May 1949, on the empty Ostend-Jabbeke motorway in Belgium, a prototype XK120 timed by the officials of the Royal Automobile Club of Belgium achieved an average of runs in opposing directions of 132.6 mph with the windscreen replaced by just one small aero screen and a catalogued alternative top gear ratio, and 135 mph with a passenger-side tonneau cover in place. In 1950 and 1951, at Autodrome de Linas-Montlhéry, a banked oval track in France, open XK120s averaged over 100 mph for 24 hours and over 130 mph for an hour. In 1952 a fixed-head coupé took numerous world records for speed and distance when it averaged 100 mph for a week.

XK120s were also highly successful in racing and rallying.
