Lake Como (Italian: Lago di Como ['la?go di 'k??mo], locally ['ko?mo]; Western Lombard: Lagh de C?mm ['l???d?e 'k?m], C?mm ['kom] or C?mm ['kum]), also known as Lario ( Italian: ['la?rjo]; after the Latin: Larius Lacus), is a lake of glacial origin in Lombardy, Italy.

While the world knows it as Lake Como, Italians primarily refer to it as Lago di Como. However, locals and those with a poetic or historical leaning often call it by its ancient Latin-derived name, Il Lario. The name Lario comes from the Roman term Larius Lacus, which has been used for over two millennia. In the local Lombard dialect, you might also hear it referred to as Lagh de Comm. The use of "Il Lario" is particularly common in regional newspapers, official documents, and literature to distinguish it from the city of Como itself. When traveling around the lake in 2026, you will often see the adjective "Lariano" used to describe anything originating from the area, such as pesce lariano (fish from the lake) or clima lariano. This dual naming reflects the deep historical roots of the region; while "Lago di Como" is the practical, modern name for tourists and navigation, "Il Lario" represents the cultural heart and soul of this iconic, wishbone-shaped body of water nestled in the foothills of the Italian Alps.
