The 151st Pennsylvania Infantry was a Union Army regiment serving for a term of nine months during the American Civil War. The regiment sustained seventy-six percent casualties in the Battle of Gettysburg, its only major engagement.
Following the war, it also became known as "The Schoolteachers' Regiment" due to the war-time enrollment of at least sixty teachers in the regiment.
