The Decoration for Officers of the Royal Naval Reserve, commonly known as the Reserve Decoration (RD) was a medal awarded to officers with at least fifteen years service in the Royal Naval Reserve (RNR) of the United Kingdom.

[2] The medal consists of the cypher of the reigning monarch in silver gilt surrounded by an oval silver cable tied with a reef knot at the base and surmounted by a gilt crown.

The reverse is plain, with later issues often engraved with the year of award.

In 1966 the Royal Naval Reserve (drawn from the Merchant Navy) and the Royal Naval Volunteer Reserve (civilian volunteers) were merged.

[4] The Reserve Decoration and the Royal Naval Reserve Long Service and Good Conduct Medal for RNR ratings were both replaced by a combined-services Volunteer Reserves Service Medal on 1 April 1999.
