Bundesautobahn 1 (translates from German as Federal Motorway 1, short form Autobahn 1, abbreviated as BAB 1 or A 1) is an autobahn in Germany. It runs from Heiligenhafen in Schleswig-Holstein to Saarbrücken in Saarland, a distance of 749 km (465 mi), but is incomplete between Cologne and Trier. B 207 continues north from Heiligenhafen to Puttgarden, at the end of the island of Fehmarn, with a ferry to Rødby, Denmark.

The part north of Hamburg is part of the Vogelfluglinie (Migratory Birds Line) and may be one day connected via a fixed link to Denmark (see below). The term Hansalinie (Hansa line) refers to the part from Lübeck (north of Hamburg, thus overlapping the Vogelfluglinie) south to the Ruhr Area (near Dortmund).
