Barlow, Pennsylvania (Horner's Mill during the American Civil War) is a populated place between the Gettysburg Battlefield and the Mason–Dixon line at the intersection of Rock Creek and Pennsylvania Route 134. North of the creek on the road summit is the principal facility of the rural community: the 1939 community hall at the Barlow Volunteer Fire Company fire station. The hall is a Cumberland Township polling place and was used by Mamie & Dwight D. Eisenhower after purchasing their nearby farm (President Eisenhower became an honorary company member in 1955). Horner's Mill was the site of an 1861 Union Civil War encampment, and the covered bridge was used by the II Corps (Union Army) and General George G. Meade en route to the 1863 Battle of Gettysburg.

Barlow is located near the U.S. Route 15 interchange to the north and has 3 Taneytown Rd intersections with the Barlow-Greenmount, Barlow, and Barlow-Two Taverns roads. South of the community is a site listed on the National Register of Historic Places (Spangler-Benner Farm) near the Mount Joy Lutheran Church and cemetery. The neighboring communities of Barlow are Greenmount 2.9 mi to the west, Round Top 3.3 mi to the north, Two Taverns 5.1 mi to the east, Harney MD 3.1 mi to the south, and Fairplay 3.2 miles to the southwest.
