The Navy Distinguished Service Medal is an award of the United States Navy and United States Marines which was first created in 1919. The decoration is considered the Navy and Marine Corps equivalent to the U.S. Army’s Distinguished Service Medal.

The Navy Distinguished Service Medal is bestowed upon any member of the Navy or Marine Corps who distinguish themselves by exceptionally meritorious service to the United States government in a duty of great responsibility. The term “great responsibility” implies senior military responsibility, and the decoration is normally only bestowed to senior Navy Flag and Marine Corps General Officers. The decoration is rarely bestowed to enlisted personnel, and then only to those who hold extremely senior enlisted positions such as the Master Chief Petty Officer of the Navy.

Additional awards of the Navy Distinguished Service Medal are annotated by gold service stars. The first award of the decoration was a posthumous presentation to Brigadier General Charles A. Doyen, USMC, who received the medal posthumously on March 13, 1919.
