Mont d'Or is a summit of the Vaud Prealps in the canton of Vaud, Switzerland, reaching 2,174 metres. It lies on the watershed between the Rhine and Rhône basins: streams on its south-eastern slope feed the Grande Eau, a tributary of the Rhône, while those on its north-western slope feed the Lac de l'Hongrin, a hydroelectric reservoir that is topographically in the Rhine basin but turbinates its water into Lake Geneva in the Rhône basin.

Mont d'Or lies on the watershed between the Rhine and Rhône basins: streams on its north-western slope feed the Lac de l'Hongrin, a hydroelectric reservoir, while those on the south-eastern side flow into the Grande Eau, a tributary of the Rhône. The Hongrin reservoir is topographically in the Rhine basin but its water is turbined into Lake Geneva in the Rhône basin.

Mont d'Or lies on the ridge between the Lac de l'Hongrin and the valley of Ormont-Dessous, above Le Sépey in the canton of Vaud, and flanks the Col des Mosses pass. The summit is reached on foot; the ridge also links it to the Gros Van (2,189 m). The mountain sits on the watershed between the Rhine and Rhône basins, so weather can shift quickly at altitude.
