The 121st Infantry Regiment is an infantry regiment of the Georgia National Guard that saw combat service in the First and Second World Wars. As a result of army-wide reorganization in the 1950s, the 121st Infantry ceased to exist as a single unit; today, various units of the Georgia National Guard trace their lineage to the 121st Infantry.
