Italian Surnames: 150 Most Common & Their Meanings

Did you know that Italy has the greatest diversity of last names in the world? There are more than 350,000 different cognomi (surnames), each carrying centuries of history, family traditions, and deep connections to Italian regions. For the more than 30 million Italian descendants in Brazil — the largest community outside of Italy — understanding the origin of the family surname is the first step toward reconnecting with your roots and, in many cases, obtaining Italian citizenship.

In this complete guide, you will discover not only the most popular Italian surnames but also understand how they were formed, what they mean, and how they can help in your journey toward recognizing Italian citizenship.

The History of Italian Surnames

Surnames in Italy emerged gradually between the 9th and 14th centuries, a period when population growth in cities made identification by first name alone insufficient. The Council of Trent (1545-1563) was fundamental in this process, as it required parishes to maintain records of baptism, marriage, and death — documents that would become essential for modern genealogical research.

How Italian Surnames Were Formed

Italian cognomi can be classified into four main categories of formation:

1. Patronymic Surnames

Derived from the name of the father or an ancestor, these are extremely common. Examples include:

• Di Giovanni — son of Giovanni
• De Luca — son of Luca
• D'Angelo — son of Angelo
• Benedetti — descendant of Benedetto

2. Toponymic Surnames

Indicate the geographical origin of the family, referring to cities, regions, or characteristics of the location:

• Romano — from Rome
• Napolitano — from Naples
• Montanari — mountain dweller
• Costa — coastal dweller

3. Occupational Surnames

Refer to the professions practiced by ancestors:

• Ferrari — blacksmith
• Sartori — tailor
• Barbieri — barber
• Molinari — miller
• Fabbri — blacksmith, craftsman

4. Descriptive Surnames

Based on physical characteristics or personality traits:

• Rossi — red-haired
• Bianchi — white-haired or fair-skinned
• Grassi — stout/large
• Piccolo — short stature
• Bruno — dark hair or skin
