The Jungfrau (German: "maiden/virgin") is one of the main summits in the Bernese Alps, situated between the cantons of Valais and Bern in Switzerland. Together with the Eiger and Mönch, the Jungfrau forms a massive wall overlooking the Bernese Oberland and is considered one of the most emblematic sights of the Swiss Alps.

The summit was first reached on August 3, 1811 by the Meyer brothers of Aarau and two chamois hunters from Valais. The ascent followed a long expedition over the glaciers and high passes of the Bernese Alps. It was not until 1865 that a more direct route on the northern side was opened.

The construction of the Jungfraujoch railway east of the summit in the early 20th century made the area one of the most-visited places in the Alps. Along with the Aletsch Glacier to the south, the Jungfrau is part of the Jungfrau-Aletsch Protected Area, which was declared a World Heritage Site in 2001.
