Lauterbrunnen (German pronunciation: [ˈlaʊtɐˌbʁʊnən]) is a village and municipality in the Interlaken-Oberhasli administrative district in the canton of Bern in Switzerland. The municipality comprises the other villages of Wengen, Mürren, Gimmelwald, Stechelberg, and Isenfluh, as well as several other hamlets. The population of the village of Lauterbrunnen is less than that of Wengen, but larger than that of the others.

The municipality comprises the Lauterbrunnen Valley (German: Lauterbrunnental), located at the foot of the Bernese Alps. It is notably overlooked by the Eiger, Mönch, Jungfrau and many other high peaks. The valley, drained by the White Lütschine, comprises the Soustal, the Sefinental and the upper Lauterbrunnen Valley with Untersteinberg. The valley includes several glaciers. Together with the adjacent valley of Grindelwald, the Lauterbrunnen Valley forms part of the Jungfrau Region of the Bernese Oberland, between Interlaken and the main crest of the Bernese Alps.

Similarly to Grindelwald, Lauterbrunnen has become a major tourist destination. It is connected to Interlaken by the Bernese Oberland Railway and is the start of the Wengernalp Railway, leading to Kleine Scheidegg. The latter resort is the start of the Jungfrau Railway, the highest railway in Europe and a gateway to the Jungfrau-Aletsch protected area.
