Brünnelistock, Mountain summit in the Schwyzer Alps, Switzerland

Brünnelistock is a 2,133-metre summit in the Schwyzer Alps, on the ridge between the Wägitalersee and the Oberseetal. It lies 1.5 km northeast of the Zindlenspitz on the same crest, which forms the natural border between the cantons of Schwyz and Glarus. South along that ridge rise the Redertenstock (2,295 m) and the Mutteristock (2,294 m).

The Brünnelistock lies on the ridge that forms the natural border between the cantons of Glarus and Schwyz, 1.5 km northeast of the Zindlenspitz. The same ridge continues south over the Ober Zindeln saddle to the double summit Redertenstock (2,295 m) and the Mutteristock (2,294 m).

The ridge carrying the Brünnelistock forms the natural cantonal border between Schwyz and Glarus, and the peak is climbed as part of the chain linking the Zindlenspitz with the double summit of the Redertenstock (2,295 m) and the Mutteristock (2,294 m). The name Brünnelistock refers to a spring, Brünneli, on the mountain.

The Brünnelistock lies on the ridge between the Wägitalersee and the Oberseetal, 1.5 km northeast of the Zindlenspitz; the same ridge continues south over the Redertenstock (2,295 m) to the Mutteristock (2,294 m). The cantonal border between Schwyz and Glarus runs along this ridge, so approach routes start from valleys on either side.

The mountain holds the 55th position among 300 peaks in Schwyz, with a prominence of 659 meters from the surrounding landscape.
