Saint-Hilaire (pronunciation), also known as Saint-Hilaire-du-Touvet (French pronunciation: [sɛ̃t‿ilɛːʁ dy tuvɛ]), is a former commune in the Isère department in the Auvergne-Rhône-Alpes region in Southeastern France.

On 1 January 2019, Saint-Hilaire was merged into the new commune of Plateau-des-Petites-Roches, alongside Saint-Bernard and Saint-Pancrasse. The commune was made up of the three smaller settlements of Saint-Hilaire, Les Margains and Les Gaudes; its town hall became that of the new commune. Its inhabitants are known in French as the Saint-Hilairois (masculine) and Saint-Hilairoises (feminine).

It is situated on the Plateau des Petites Roches, a natural balcony above the valley of the Isère, on the east side of the Massif de la Chartreuse and overlooked by the peak of the Dent de Crolles.
