Harrison H. Jeffords (August 21, 1836 – July 3, 1863) was the Colonel of the 4th Michigan Volunteer Infantry Regiment in the Union Army of the Potomac during the American Civil War.

Jeffords was born in New York, but his family eventually moved to Michigan, where Harrison soon took up the study of law.

The Fourth Michigan Infantry and Harrison Jeffords saw action in several of the major battles in the Eastern Theater while serving in the Army of the Potomac.

His body was sent home to Dexter, Michigan, after the battle, where approximately 2,000 people attended the funeral of its beloved hero.

Despite popular belief, the monument's image of the color-bearer is not a representation of Colonel Harrison Herbert Jeffords.
