Lake Maggiore (Italian: Lago Maggiore, pronounced [ˈlaːɡo madˈdʒoːre] lit. 'Great Lake' or Verbano [verˈbaːno]; Latin: Lacus Verbanus) is a large lake located on the south side of the Alps. It is the second largest lake in Italy and largest lake of the canton of Ticino, Switzerland. Lake Maggiore is the most westerly of the three great prealpine lakes of Italy, it extends for about 70 km between Locarno and Arona.

The climate is mild in both summer and winter, producing Mediterranean vegetation, with beautiful gardens growing rare and exotic plants. Well-known gardens include those of the Isola Madre, Isola Bella and the Isole di Brissago, that of the Villa Taranto in Verbania, and the Alpinia botanical garden above Stresa.

Lake Maggiore is 68 km long, with a breadth which varies from 3 to 5 km, except at the bay opening westward between Pallanza and Stresa, where this reaches 10 km. It exceeds all the other Italian lakes in length, but in the extent of surface it falls considerably below the Lake Garda. Its mean height above the sea level is 193 metres; but as its depth greatly exceeds that measurement, the bed is almost everywhere considerably below the sea-level, and reaches no less than 179 metres below the sea. Its form is very sinuous, so that there are few points from which any considerable part of its surface can be seen at a single glance. If this lessens the effect of the apparent size, it increases the variety of its scenery. While the upper end is completely alpine in character, the middle region lies between hills of gentler form, and the lower end advances to the verge of the plain of Lombardy.
