The Arms of Canada (French: armoiries du Canada), also known as the Royal Coat of Arms of Canada (French: armoiries royales du Canada) or formally as the Arms of Her Majesty The Queen in Right of Canada (French: Armoiries de Sa Majesté la Reine du chef du Canada) is, since 1921, the official coat of arms of the Canadian monarch and thus also of Canada. It is closely modelled after the royal coat of arms of the United Kingdom with French and distinctive Canadian elements replacing or added to those derived from the British version.

The maple leaves in the shield, blazoned "proper", were originally drawn vert (green) but were redrawn gules (red) in 1957 and a circlet of the Order of Canada was added to the arms for limited use in 1987. The shield design forms the monarch's royal standard and is also found on the Canadian Red Ensign. The Flag of the Governor General of Canada, which formerly used the shield over the Union Flag, now uses the crest of the arms on a blue field.

 The arms are embossed on the cover of any citizen's Canadian passport, in order to legally signify and symbolize that the bearer is travelling under the aid of the Crown of Canada.
