Mont Maudit, Alpine summit in Chamonix-Mont-Blanc, France and Courmayeur, Italy.

Mont Maudit is an alpine summit standing at about 4,465 meters (14,645 feet) between Mont Blanc du Tacul and Mont Blanc along the France-Italy border. The peak forms part of the Mont Blanc massif and is accessed via the northwest ridge from Col du Mont Maudit.

The first ascent was made on 12 September 1878 by Henry Seymour Hoare and William Edward Davidson, with guides Johann Jaun and Johann von Bergen, via the south ridge during an ascent of Mont Blanc by the Corridor route. The southeast Frontier or Kuffner ridge was first climbed on 4 July 1887 by Moriz von Kuffner with Alexander Burgener and Josef Furrer. In 1820 an avalanche on the mountain killed three guides during an expedition led by Joseph Hamel, the first fatal accident on a Mont Blanc ascent.

The French name means "Cursed Mountain"; until the end of the 18th century, Mont Blanc and its satellite peaks were collectively called the Montagne Maudite. The name later attached to this summit alone, which climbers reach from the Refuge des Cosmiques or the Col du Trident.

Technical climbing at this elevation demands experience and proper acclimatization before attempting the route. Climbers should verify their gear and prepare for rapid weather changes common at this altitude.

The southeast or Frontier ridge, also called the Kuffner ridge, was first climbed from 2 to 4 July 1887 by Moriz von Kuffner with guides Alexander Burgener and Josef Furrer. George Mallory made only the third ascent in 1911, in a party led by R. L. G. Irving. Ascents start from the hut on the Col du Trident and take at least seven to eight hours.
