Austria3 was a conglomerate of three Austrian quite individualist singer-songwriters Wolfgang Ambros, Georg Danzer and Rainhard Fendrich.

The group was initiated by Fendrich in order to give one single charity concert in favour of homeless in 1997 (which collected more than ATS 2 million, almost USD 200,000). Their success as a group was overwhelming, and the three individualists showed up on stage as Austria3 from that day on, until they decided to stop that project, which they announced on 10 June 2006. Their last concert was given at Altusried, Germany, on 26 July 2006.
