Mont d'Arbois, Mountain summit in Haute-Savoie, France.

Mont d'Arbois is a mountain summit near Saint-Gervais-les-Bains that rises to approximately 1833 meters and features a broad plateau with meadows and scattered buildings. From this location, one can see Mont-Blanc and other Alpine peaks in the distance.

In 1921 Noémie de Rothschild developed the Domaine du Mont d'Arbois here, turning the slopes into a ski and leisure area above Megève. During World War II the journalist Émile Servan-Schreiber hid in his "Chalet Nanouk" on the mountain with his Jewish family, including his Yiddish-speaking mother. The summit itself, above 1,600 to 1,700 metres, lies entirely within Saint-Gervais-les-Bains, while the lower slopes belong to Megève, Demi-Quartier and Combloux.

The name Arbois may come from the Latin alba, white, referring to the pale rock of the summit. The mountain's two tops, 650 metres apart, both carried the name; until the 1950s it designated the 1,827-metre northwestern knoll, then shifted to the 1,839-metre southeastern point. A radio transmitter on the summit broadcasts Radio Mont-Blanc on 94.6 MHz.

The summit is reached by the Mont d'Arbois, Princesse and Bettex-Mont d'Arbois cable cars, plus the Idéal Sport and Mont d'Arbois chairlifts; the GRP Tour du Pays du Mont-Blanc also crosses the slopes on foot. Above 1,600–1,700 m the whole summit lies in Saint-Gervais-les-Bains, so lift tops and bottoms sit in different communes. An astronomical observatory run by an association stands at 1,800 m between the two summits.

During World War II, journalist Émile Servan-Schreiber hid at Mont d'Arbois in his "Chalet Nanouk" with his Jewish family, including his Yiddish-speaking mother. The chalet stood on slopes that had been developed since 1921 as the Domaine du Mont d'Arbois by Noémie de Rothschild.
