Rougemont (French pronunciation: [ʁuʒmɔ̃] ) is a municipality in the Pays-d'Enhaut of the canton of Vaud in Switzerland.

Rougemont is first mentioned in 1115 as Rubeus Mons and Rogemot. The name of the village also appears in various forms in medieval chronicles: Rubeimontis, Rogemont, Rubeo monte, Rogo mons, and Rojomont. The name stems from the red rock outcroppings north of the village. The site was probably first settled by a religious order coming from Cluny in France, which had received the land in 1080 from the Count of Gruyère. In 1569, the priory was replaced by the château of Rougemont, which became the residence of the bailiffs of Bern, who succeeded the Count of Gruyère. The area became part of the canton of Vaud in 1798.

Diana, Princess of Wales lived for some time at the city, in the late 1970s while a student at the Institut Alpin Videmanette.

The Swiss Reformed Church of Saint-Nicolas de Myre is listed as a Swiss heritage site of national significance. Both the village of Rougemont and the hamlet of Flendruz are part of the Inventory of Swiss Heritage Sites.

The village is built essentially on a single east-west axis, with houses on both sides of the street facing south to catch the sun. There is room for flower and vegetable gardens. All the houses are typical chalets, which are very close to one another; sometimes their roofs touch. Some of the homes are over 300 years old.

The former priory chapel of Saint-Nicolas is now a Protestant church. The church is in the form of a cross and has retained some of its romanesque elements. It was remodeled between 1585 and 1587, when the choir was replaced with three semi-circular apses. The roof in the typical style of the Bernese Oberland dates from the 17th century.
