Signal du Génie is a mountain summit in the French Alps situated between the municipalities of Saint-Julien-Mont-Denis and Saint-Martin-de-la-Porte. The peak features steep rock faces and ridges that rise distinctly above the surrounding valleys.
The peak served as a military observation post during Alpine campaigns, allowing forces to monitor movements across multiple valleys and control key mountain passages. This strategic role shaped its importance in regional defense networks.

The ascent requires climbing experience and proper equipment, with approach routes available from different valleys on either side of the peak. Routes vary in difficulty and should only be attempted by experienced mountaineers.
Its location straddling two municipalities creates distinct approach routes from different valleys, each offering varied perspectives of the Alpine landscape. This position reveals different aspects of the surrounding mountain formations from each side.
