The Merchant Navy Medal for Meritorious Service is a state award within the British honours system.

The medal is awarded to no more than 20 recipients annually who are announced on Merchant Navy Day, 3 September.

Recipients must have shown particularly valuable devotion to duty and exemplary service so as to serve as an outstanding example to others.

The reverse depicts the badge of the Merchant Navy: the letters MN surrounded by a rope joined at the base by a reef knot, a naval crown surmounts the rope, with the inscription 'FOR MERITORIOUS SERVICE'.

[5] The medal hangs from a ring suspension, with the 1.25 inches (32 mm) wide ribbon made up of equal stripes of green at the edges, white in the centre, with red bordering the white stripe which represent marine navigational lights.
