The Fort Wayne Line and Fort Wayne Secondary is a rail line owned and operated by the Norfolk Southern Railway (NS), Chicago, Fort Wayne and Eastern Railroad (CFE), and CSX Transportation in the U.S. states of Pennsylvania, Ohio, and Indiana. The line runs from Pittsburgh, Pennsylvania west via Fort Wayne, Indiana to Gary, Indiana along what was once the Pennsylvania Railroad's Pittsburgh to Chicago Main Line.

From downtown Pittsburgh, at the west end of the Pittsburgh Line, west to the junction with CSX's Greenwich Subdivision at Crestline, Ohio, NS owns the line. Major junctions include the Conemaugh Line in northern Pittsburgh, the Cleveland Line at Rochester, Pennsylvania, the Youngstown Line at New Brighton, Pennsylvania, the Lordstown Secondary east of Alliance, Ohio, and the Cleveland Line again at Alliance.

From Crestline west to Adams junction in Allen County, Indiana (Fort Wayne Line) and beyond to the Gary, Indiana neighborhood of Tolleston (Fort Wayne Secondary), the line is owned by CSX. Since 2004 this section has been leased to and operated by RailAmerica's Chicago, Fort Wayne and Eastern Railroad (CFE), with NS retaining trackage rights.
