List of American Civil War Medal of Honor recipients: G–L

This is a brief historical summary regarding the American Civil War Medal of Honor recipients whose last names begin with letters G through L. During this period of American military history, the Medal of Honor was established as the nation's premier decoration to recognize soldiers, sailors, and marines who distinguished themselves by gallantry and intrepidity at the risk of their lives above and beyond the call of duty.

Many of the decorations earned during the Civil War were awarded for the critical action of capturing or saving regimental flags. In the context of 19th-century warfare, these colors served as the vital rallying point and directional guide for military units during the chaos of battle. The loss of a regimental flag could cause severe disruption to a unit's cohesion and command structure, often carrying greater tactical consequences than the loss of its commanding officer.

The Medal of Honor remains the highest military decoration awarded by the United States government. While it was frequently awarded for flag captures during the Civil War, its criteria have evolved over time to maintain its status as the most prestigious recognition of valor in the United States armed forces.
