The Lepontine Alps (,, ) are a mountain range in the north-western part of the Alps. They are located in Switzerland (Valais, Ticino, Uri and Graubünden) and Italy (Piedmont and Lombardy). The Simplon rail tunnel (from Brig to Domodossola) the Gotthard rail (from Erstfeld to Bodio) and Gotthard road tunnels (from Andermatt to Airolo) and the San Bernardino road tunnel are important transport arteries. The eastern portion of the Lepontine Alps, from the St Gotthard Pass to the Splügen Pass, is sometimes named the Adula Alps, while the western part is historically referred to as the Ticino Alps. Etymology The designation Lepontine Alps, derived from the Latin name of the Val Leventina, has long been somewhat vaguely applied to the Alpine ranges that enclose it, before being used for the whole range.

Los Alpes Lepontinos (,, ) son una franja montañosa en la parte noroeste de los Alpes. Se encuentran en Suiza (Valais, Ticino, Uri y Graubünden) e Italia (Piedmont y Lombardía). El túnel ferroviario Simplon (de Brig a Domodossola) el ferrocarril Gotthard (de Erstfeld a Bodio) y los túneles de carretera Gotthard (de Andermatt a Airolo) y el túnel de carretera San Bernardino son importantes arterias de transporte. La parte oriental de los Alpes Lepontinos, del paso de San Gotthard al paso de Splügen, se llama a veces los Alpes Adula, mientras que la parte occidental se refiere históricamente a los Alpes Ticino. La etimología de la designación de los Alpes Lepontinos, derivada del nombre latino del Leventina, ha sido un poco vaguamente aplicada a las franjas alpinas que enclose, antes de ser utilizada para la división geográfica en toda la región.
