Nathan Huntley Edgerton (August 28, 1839 – October 27, 1932) was a Union Army officer who received the Medal of Honor for gallantry in the American Civil War.

By 1858, his father had remarried to Anna Mikkel Stratton (1817–1897) by whom Nathan gained a half-brother and two half-sisters, all of whom survived to adulthood.

Upon completion of his education, he became a schoolteacher and was listed in the 1860 census as a teacher on the faculty of the Westtown School in West Chester, Pennsylvania.

However, having been born and raised as a Quaker, Edgerton did not join the war until 1863, when the Army of Northern Virginia invaded Pennsylvania.

In the early morning of September 29, 1864, his regiment advanced against the Confederate line at the Battle of New Market Heights in Virginia.

The three men, Edgerton, Hawkins, and Kelly are depicted in a painting, Three Medals of Honor by artist Don Troiani.

Upon his return to Philadelphia, he and his family moved to Schuylkill Township where they bought a home, and he found employment as a General Supervisor of Personnel for the Pennsylvania Railroad.

By 1900, Edgerton and his wife were renting a farm in Lower Providence Township with their youngest son, Ralph, as Nathaniel worked as an electrician.

Some time before 1910, Edgerton and his wife moved to a farm in Agness, Oregon, that they purchased with their son Ralph.

Despite initial plans for his burial at Arlington National Cemetery, his family instead chose to bury him on the farm beside Esther Lu.
