This is an incomplete list of the last surviving veterans of American wars. Exactly who is the last surviving veteran is often an issue of contention, especially with records from long-ago wars. The "last man standing" was often very young at the time of enlistment and in many cases had lied about his age to gain entry into the service, which confuses matters further.
