The Niesen is a mountain peak of the Bernese Alps in the Canton of Bern, Switzerland.

It overlooks Lake Thun, in the Bernese Oberland region, and forms the northern end of a ridge that stretches north from the Albristhorn and Mannliflue, separating the Simmental and Kandertal valleys.

[3] Administratively, the summit is shared between the municipalities of Reichenbach im Kandertal to the southeast, and Wimmis to the west and north.

[3] The summit can be reached easily by using the Niesenbahn funicular from Mülenen (near Reichenbach).

[citation needed] The Niesen may have influenced some modernist paintings by Paul Klee, in which an abstracted pyramidal form is seen.
