Arona (Italian pronunciation: [aˈroːna]; Piedmontese: Aron-a [aˈrʊŋa]; Western Lombard: Aruna [aˈruna]) is a town and comune on Lake Maggiore, in the province of Novara (northern Italy).

This historical importance is reflected in the artifacts discovered from a Roman necropolis, including urns, terracotta pots, and coins, which are currently exhibited in the city museum in Piazza San Graziano.

After the siege and destruction of Milan in 1162 by Emperor Frederick Barbarossa, many of the exiled took refuge in Arona.

In 1538 Carlo Borromeo was born in the Castle on the Rock of Arona, becoming one of the town's most significant figure.

Around there are the hilly bas-reliefs of morainic origin incorporated into the Lagoni di Mercurago Natural Park where, in 1860, the first pile-dwelling settlement found in Italy was identified.

33% of the surface is occupied by urbanized areas, 9% by meadows or pastures; smaller percentages are allocated to parks, gardens and green sports areas (2.3%), vegetable gardens, orchards, nurseries and vineyards (1.7%), uncultivated herbaceous (1%) and arable land (0.4%).
