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). Its main economic activity is tourism, especially from Milan, France and Germany.

Archaeological findings have shown that the area of what today is Arona was settled from the 18th–13th centuries BC. Prehistoric pile-dwellings have been found near the town and are part of the Prehistoric Pile dwellings around the Alps UNESCO World Heritage Site. Later, it was a possession of the Celts, the Romans and the Lombards.

In the era of the Roman Empire, Arona became an essential waypoint of the Simplon route, used by the Roman army for the conquest of Gaul region. 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.
