Wolfgangsee is a lake in Austria that lies mostly within the state of Salzburg and is one of the best known lakes in the Salzkammergut resort region.
The Wolfgangsee stretches about 10.5 kilometres from the northwest to the southeast. It is divided into two parts by a peninsula, called die Enge (the Narrow), situated roughly in the middle of its southern shore opposite St. Wolfgang, where the breadth is no more than 200 metres. The western portion of the lake at St. Gilgen is known as the Abersee.
The lake has an area of about 12.9 to 13.1 km² and is surrounded by the Salzkammergut mountain range. On the northern side, the Schafberg is located. A rack railway, the Schafbergbahn leads up to the summit at 1,782 m. Due to the steep shore at its foot only a footpath connects St. Wolfgang and the village of Ried with St. Gilgen along theFalkensteinwand, the set of the Bergpsalmen ("mountain psalms") lyric anthology written by Joseph Viktor von Scheffel in 1870. In the south and southwest of the Wolfgangsee lies the Osterhorngruppe, with heights up to 1,800 metres. Directly south of St. Gilgen rises the Zwölferhorn (1,521 m), which can be visited by cable car.
The settlements around the lake, especially St. Wolfgang and St. Gilgen are popular resort towns, mainly in summer. Furthermore the area around the lake was the location of several Heimatfilm movies, suggesting an untouched alpine idyll.
