George Edwin Lord (February 17, 1846 – June 25, 1876) was a U.S. Army Assistant Surgeon in the 7th Cavalry who was killed in the Battle of the Little Big Horn in Montana Territory during the Black Hills War.

He entered into another contract with the U. S. Army in January 1875 and was made a first lieutenant in the 7th Cavalry, posted in Fort Abraham Lincoln in the Dakota Territory.

Dr. Lord's body was not positively identified by the first burial crews, and he was initially listed by General Alfred H. Terry and others as missing in action.

Captain Otto E. Michaelis and Lieutenant Richard E. Thompson, however, later contacted Lord's brother with their belief that a body sighted on the field had been the doctor's, based on a blue shirt the corpse was wearing as well as "the shapely hands, the moustache, and general appearance.

In 1890, a marker for Lord was placed on the so-called South Skirmish Line, based on the discovery there of buttons that were thought to be part of a staff officer's uniform which doctors would wear.
