The Augsburg–Buchloe railway is a double-track main line in the German state of Bavaria.

It was built as part of the Ludwig South-North Railway, one of the oldest lines in Germany.

The route was created as part of the Ludwig South-North Railway from Lindau via Kempten, Augsburg and Nuremberg to Hof.

The construction of the 60.2 km long line from Augsburg Hauptbahnhof via Bobingen and Buchloe to Kaufbeuren was authorised by a Bavarian law of 25 August 1843 and opened on 1 September 1847.

The 20.3 km long section from Buchloe to Kaufbeuren is now considered part of the Buchloe–Lindau railway.
