An honor guard, or ceremonial guard, is a ceremonial escort, often military in nature, usually composed of volunteers who are carefully screened for their ability and physical dexterity. Only those persons who are highly motivated and maintain exceptionally high standards of appearance and conduct and show aptitude for ceremonial duty are considered. The primary purpose of an honor guard is to provide funeral honors for fallen comrades.

An honor guard may also serve as the "guardians of the colors". They present a nation's colors for various ceremonies and official state functions, both on and off base. Additionally, honor guards serve as ambassadors to the public, presenting a positive image of their service, and assisting with the recruiting effort.
