cantoni

Cantoni is a surname of Italian origin. It is borne by individuals in Italy and by Italian diaspora communities around the world, including in the Americas and Europe. As with many Italian surnames, Cantoni likely originated from toponymic or occupational roots, and it may denote descent from a place associated with a cantone or simply be a family name that arose in a locality.

In Italian, cantoni is the plural form of cantone. The term cantone refers to a canton or district—an administrative or geographic subdivision found in several countries, notably including Switzerland. When written as a proper noun in Italian, the plural form Cantoni is used to refer to the Swiss cantons collectively, e.g., i Cantoni svizzeri.

As a surname and as a broader linguistic term, Cantoni appears in biographical, genealogical, and historical sources. The name does not correspond to a single widely known figure or institution but is part of the broader category of Italian toponymic surnames.
