The Pyhrnautobahn (A9) ('Pyhrn Motorway') is an Autobahn (motorway), in Austria. It runs through Alps by 2 two-lane tunnels: the convert|5400|m|ft|adj=on|sp=us long Bosrucktunnel and the convert|8320|m|ft|adj=on|sp=us long Gleinalmtunnel. The longest tunnel on the motorway is the convert|10|km|mi|0|adj=on|sp=us long Plabutschtunnel under Graz and its outskirts.

The last section of the highway was built in 2004. Some parts still have only a single roadway, including some tunnels.

The motorway south of the A2 interchange is a part of the Pan-European corridor Xa.
