Palfnerkogel, Mountain summit in Sankt Johann im Pongau, Austria.

Palfnerkogel is a mountain peak in the Dientener Berge range that stands at 1413 meters elevation and sits between Sankt Johann im Pongau and Bischofshofen. The summit provides views over surrounding valleys and passes through diverse terrain as visitors ascend.

Copper ore was mined on the Palfnerkogel from prehistoric times, with a prospecting working at Einöden dated to the 2nd millennium BC. Three west-east lodes were worked: the Birgsteingang in the Joseph and Walpurgastollen (1855–1879), the Burgschwaiggang in the Klara and Luisenstollen, and the Brandergang, reopened in the early 20th century and mined until 1957, when about 20 t of ore a day at 1.4–1.8 % copper were still extracted.

The name Palfen comes from the local word for rock, and the hamlet Palfner Dörfl at the eastern foot of the ridge carries it. The Arthurstollen, a protected monument, is set up as a show mine and is to be presented within the Geopark Erz der Alpen, as is the Hochglocker mining area.

Visitors typically begin their hike from Sankt Johann im Pongau following clearly marked trails. The route is accessible to those with moderate fitness, and the path offers several spots to rest along the way.

The Arthurstollen, a protected mining tunnel on the mountain's slope, is set up as a show mine and is to be presented within the Geopark Erz der Alpen, together with the Hochglocker mining area. The last mining period yielded about 20 tonnes of ore daily at 1.4–1.8% copper before it ended in 1957.
