Gatto
An Italian surname from a word for a cat, probably first used as a nickname for a quick, sly, or cat-like person.
The #7,421 most common surname in the United States (2010 Census) — about 1 in every 68,824 Americans shares it.
Etymology
Gatto is the Italian word for "cat," ultimately from Latin cattus. As a surname, it most likely began as a nickname, applied to someone thought to resemble a cat in looks, habits, or temperament. In older surname scholarship, similar forms are sometimes linked to Germanic nickname traditions as well, but for the Italian surname the cat-word explanation is the clearest and most widely accepted.
History
The surname is especially associated with Italy, where it remains most common in the south and in Sicilian and southern Italian communities more broadly. It has also spread through Italian migration to the Americas and other diaspora regions. Historical surname writers sometimes discussed Gatto alongside shorter pet forms and nickname patterns, which reflects how flexible medieval by-names could be before surnames became fixed.

Fun fact
Because gatto literally means "cat," the surname belongs to a very large European family of cat-based surnames, a common source of medieval nicknames.
