Bundesautobahn 30 (translates from German as Federal Motorway 30, short form Autobahn 30, abbreviated as BAB 30 or A 30) is a highway in northwestern Germany.

It is an important connection from Hannover and Minden to Osnabrück, Münster and the Netherlands, and part of European Route E 30.

In its course towards the east it first crosses Bundesautobahn 31 near Schüttorf, offering connections towards the Ruhr area (south) and Emden (north).

The government of the region Detmold has issued a planning decision for this last segment of the A 30 at the request of the North Rhine-Westphalian state company for road construction in January, 2007.

The citizens' group which exerts itself against the construction of the highway has submitted a complaint and an application for granting temporary legal protection against the planning decision before the Federal Administrative Court.
