St. Wolfgang im Salzkammergut is a market town in central Austria, in the Salzkammergut region of Upper Austria, named after Saint Wolfgang of Regensburg.

Wolfgang of Regensburg was bishop of Regensburg in Bavaria from Christmas 972 until his death. He is a saint in the Catholic and Eastern Orthodox churches. He is regarded as one of the three great German saints of the 10th century, the other two being Ulrich of Augsburg and Conrad of Constance. Towards the end of his life Wolfgang withdrew as a hermit to a solitary spot, in the Salzkammergut region of Upper Austria. Soon after Wolfgang's death many churches chose him as their patron saint, and various towns were named after him.
