The Ashburton Shield is an historic trophy for rifle shooting in the United Kingdom. It is awarded annually to the winning team-of-8 at the Schools Imperial Meeting, held by the National Rifle Association at Bisley. The competition is open to teams of cadets from (predominantly) Combined Cadet Force units based in public and independent schools. A separate competition is held the week prior for cadet units not attached to a school (such as the Army Cadet Force), as part of the Service Rifle Imperial Meeting.
