The Canadian Forces Decoration (post-nominal letters "CD") is a Canadian award bestowed upon members of the Canadian Forces who have completed twelve years of military service, with certain conditions. By convention, it is also given to the Governor General of Canada upon his or her appointment as viceroy, which includes the title of Commander-in-Chief in and over Canada. The decoration is awarded to all ranks, who must have a good record of conduct during the final eight years of claimed service.

The first Governor General to receive the CD was Viscount Alexander of Tunis in 1951. The medal was initially awarded to all members of the Royal Family who served in the Canadian Forces, even without completion of twelve years of service; this has, however, not been automatic since 1953.
