The Emperor Ferdinand Northern Railway (German: Kaiser Ferdinands-Nordbahn; Czech: Severní dráha císaře Ferdinanda; Polish: Kolej Północna Cesarza Ferdynanda) was a railway company during the time of the Austrian Empire. Its main line was intended to connect Vienna with the salt mines in Bochnia near Kraków. The name is still used today in referring to a number of railway lines formerly operated by that company.
