(Fr. écurie, a stable), an officer who has the care and management of the horses of a king or prince.

The equerries of the royal household in England are certain officers under the Master of the Horse, the first of whom is styled chief equerry and clerk-marshal, and has a salary of £500 a-year. The royal equerries in rotation attend the sovereign when riding abroad in state. Other members of the royal family are likewise attended by equerries.
