Harford County sits at the top of the Chesapeake Bay. The Susquehanna River flows along the eastern border of the county to enter the Bay at Havre de Grace. Other major waterways include the Gunpowder Falls and the Bush River. Much of Harford County is characterized by the rolling hills of the Piedmont Plateau, but the southeast corner is part of the Atlantic Coastal Plain. The county has a mix of rural and suburban areas, but also includes some forested tracts. The highest elevation is 805 feet in the county’s northwestern corner.

Harford County is bordered by the state of Pennsylvania to the north; Cecil County to the east, across the Susquehanna River; Baltimore County to the west; and Kent County to the southwest, on the Eastern Shore of the Chesapeake Bay. The border between Harford and Kent is in the middle of the Bay.

I-95, US Route 1, and US Route 40 are major corridors through Harford County, all running roughly parallel to one another, oriented slightly northeast-southwest.  Major north-south roadways are MD Routes 152, 24, 543, and 22.
