Interstate 83 (abbreviated I-83) is an Interstate Highway in the Eastern United States. Its southern terminus is in Baltimore, Maryland at a signalized intersection with Fayette Street; its northern terminus is in Harrisburg, Pennsylvania at I-81.

Most of the route south of Lemoyne, Pennsylvania is a direct replacement of U.S. Route 111 (US 111), a former spur of US 11.

The Jones Falls Expressway, known to local residents as the JFX, is a 10.2-mile-long (16.4 km) freeway that carries I-83 from downtown Baltimore to the northern suburbs. It is the area's true north–south artery, because I-95 runs mostly east–west through much of the city. Its southern terminus is at Fayette Street, and its northern terminus is at Maryland Route 25 (MD 25), just north of the Baltimore Beltway (I-695). Inside Baltimore, the road is maintained not by the Maryland State Highway Administration, which controls most freeways in the state, but by the city's Department of Transportation.
