The 20th Pennsylvania Volunteer Infantry (Scott Legion) was a volunteer infantry regiment in the Union Army during the American Civil War. One of the Keystone State's three-month service regiments, this unit's tour of duty took its members from Philadelphia to South Central Pennsylvania and then southeast to Maryland and Virginia (into Martinsburg and other areas that are now part of West Virginia).
