The Fort Henry Guard (FHG) is a historical interpretation and exhibition drill organization based at Fort Henry, a national historic site in Kingston, Ontario, Canada. It has recreated the British military tradition of a bygone era since its founding in 1938. The Guard seeks to interpret in an entertaining and animated manner, a snapshot of life in the British Army of Queen Victoria, when Canada was part of the British Empire. The Guard also practices and performs historic military drill, demonstrated during daily inspections, cannon firings and garrison parades in addition to the weekly Sunset Ceremonies. Guard members dress in the standard line infantry uniforms of a British regiment and the standard gunner's uniforms of the Royal Artillery in the year of 1867, but the Guard does not represent any specific infantry regiment that garrisoned the fort.

Exhibition drill is a variant of drill that involves complex marching sequences which usually deviate from drill used in the course of ordinary parades. Teams performing exhibition drill are often affiliated with military units, but the scope of exhibition drill is not limited to military drill teams. Exhibition drill is often performed by Armed Forces Precision Drill Teams, the drill teams at service academies and ROTC and JROTC units, and civilian drill teams that perform at parades, drill meets, and half-time shows and other public venues.
