The Jaguar Mark IV (pronounced mark four) is a range of automobiles built by Jaguar Cars from 1945 to 1949. The cars were marketed as the Jaguar 1½ litre, Jaguar 2½ litre and Jaguar 3½ litre with the Mark IV name later applied in retrospect to separate this model from the succeeding Mark V range.

The range was a return to production of the SS Jaguar 1½ litre, 2½ litre and 3½ litre models produced by SS Cars from 1936 to 1940.^[1] Before World War II the model name Jaguar was given to all cars in the range built by SS Cars Ltd with the saloons titled SS Jaguar 1½ litre, 2½ litre or 3½ litre and the two-seater sports cars the SS Jaguar 100 2½ litre or 3½ litre. In March 1945 the company name SS Cars Ltd was changed to Jaguar Cars Ltd.^[2]

All the Mark IVs were built on a separate chassis frame with suspension by semi-elliptic leaf springs on rigid axles front and rear.
