Theodore Lane Sampley was an American Vietnam War veteran and activist. He primarily advocated for those servicemen still considered missing in action or prisoners of war (POW-MIA) as of the end of hostilities in 1975. A staunch political conservative, he also ran for local political office several times. He is credited with the research that identified Air Force Lt. Michael Blassie as the Vietnam fatality buried at the Tomb of the Unknown Soldier, and for his role in organizing the annual Rolling Thunder motorcycle event in Washington. In Kinston, North Carolina, where he lived for much of his adult life, he was known for his local civic activism, most notably his effort to build a replica of the Confederate ironclad CSS Neuse, the only full-size replica of a Confederate ironclad, in the city's downtown.
