Grande Rousse, Mountain summit in Aosta Valley, Italy

Grande Rousse is a 3,607 m mountain in the Graian Alps of Aosta Valley, Italy, the highest point of the ridge between the Rhêmes and Valgrisenche valleys. It has two summits about 800 m apart: Punta Nord (3,607 m) and Punta Sud (3,577 m), separated by the Col de la Grande Rousse (3,516 m). The steep eastern face rises above the Rhêmes valley, while the normal route climbs the opposite side.

The first recorded ascent of Grande Rousse was made in 1864. The mountain rises to 3,607 m and is the highest point of the ridge dividing the Rhêmes valley from the Valgrisenche. Its two summits, Punta Nord at 3,607 m and Punta Sud at 3,577 m, are about 800 m apart and separated by the Col de la Grande Rousse at 3,516 m.

The name Grande Rousse looks French for "large tawny", but in the Valdostan patois Ruise-Roése-Roise-Royse it means glacier, the same root behind Monte Rosa. On the Valgrisenche side the mountain is largely covered by the Ghiacciaio dell'Invergnan. It is also called Becca d'Invergnan or Becca d'Invergnaou.

The normal route starts at Usellières, a hamlet of Valgrisenche, and reaches the Bivacco Luigi Ravelli at 2,860 m. From there climbers cross the Ghiacciaio dell'Invergnan, then the steep slope up to the Col de la Grande Rousse (3,516 m), and finish along the south ridge of the Punta Nord. The eastern side above the Rhêmes valley is the steepest and is not the ascent line.

The mountain has two summits about 800 metres apart: Punta Nord at 3,607 m and Punta Sud at 3,577 m, divided by the col de la Grande Rousse at 3,516 m. The normal route reaches Punta Nord via the south ridge after climbing the Invergnan glacier from the Ravelli bivouac.
