Courmayeur (French: [kuʁmajœʁ] ⓘ; Italian pronunciation: [kurmaˈjɛr]; Valdôtain: Croméyeui) is a town and comune in northern Italy, in the autonomous region of Aosta Valley.

The Mont Blanc Tunnel, connecting Courmayeur with Chamonix, opened in 1965, and provides an important road link between Italy and France.

Courmayeur shares administration of Mont Blanc with its neighboring municipality of Saint-Gervais-les-Bains in France, and is consequently able to claim the title of highest commune in Italy.

Courmayeur also shares access to the glacial ski run of the Vallée Blanche with another French town, Chamonix, which sits at the opposite, northern, side of the Mont Blanc massif.

[6] The nearby village of La Palud is the base station of the Skyway Monte Bianco, the cable car to the Pointe Helbronner.
