The Medium Mark III was a medium tank developed by the United Kingdom during the Interwar period.

The prototypes of the Medium Mark II were the three A6 also known as "16-tonner" tanks. From the tests of the A6, three Mark IIIs were built and put into service with the British Army but due to the high cost no more were purchased.
