The Military Medal was (until 1993) a military decoration awarded to personnel of the British Army, and formerly also to personnel of the armies of other Commonwealth countries, below the rank of Warrant Officer, for bravery in the battlefield.

The medal was established on March 25, 1916. It was equivalent to the Military Cross which was awarded to commissioned officers and Warrant Officers. Recipients of the Military Medal were entitled to use the post-nominal letters "MM". In 1993 the Military Medal was discontinued, and since then the Military Cross can be awarded to British Army personnel of all ranks.

The ribbon was dark blue, with three white and two red stripes at the centre.
