Lake Wolfgang (German: 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 municipalities on its shore are Strobl, St. Gilgen with the villages of Abersee and Ried as well as the market town of St. Wolfgang in the state of Upper Austria. The town and the lake are named after Saint Wolfgang of Regensburg, who, according to legend, built the first church here in the late 10th century.
Lake Wolfgang 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.
