The Fredericia–Aarhus railway line is a 108.5 km long standard-gauge double-track railway line in Denmark which runs between the cities of Fredericia and Aarhus in East Jutland. It constitutes a section of the East Jutland longitudinal railway line, the through route along the east coast of the Jutland Peninsula from the German border at Padborg to the port city of Frederikshavn in North Jutland. The railway opened in 1868. The line is owned and maintained by Rail Net Denmark and served with passenger trains by the railway companies DSB and Arriva.

Future

As part of plans for high-speed rail in Denmark, a new section of track between Hovedgård and Hasselager, bypassing Skanderborg, is planned.
