Esposito is a surname of Italian provenance, its etymology deriving from the Latin word expositus which translates as “exposed” or “abandoned.” The term was historically applied to infants who were left outside, often at the threshold of a church or convent, where they would be collected by clergy or municipal authorities for care and eventual baptism.

During the medieval period, a system of foundling wheels was common in Italy; these safe spaces regularly accepted unwanted babies. Those infants were baptised with the identifier Esposito as a reminder of their state of exposure and the goodwill of those who had taken them in. The name thereby became a means of providing a surname for children without recorded lineage.

Variants of the surname appear throughout Italian history—including Esposuto, Esposto, Esposti, Exposi, Espote, Sposito, and the Spanish adjective Exposito—each reflecting regional dialects or orthographic practices. The name is particularly frequent in the southern parts of the country, notably in Naples, Campania, Apulia, and Sicily, where it has become one of the most common family names.

Heraldic records reveal that a coat of arms was granted in France to a bearer of this surname; the blazon describes a gold field with a base of a rock supporting a black eagle, and a red chief pierced with three silver crosses. Italian church registers document early bearers such as Francesco Esposito of Casale di Posilipo, Napoli, dated 12 April 1760, and Maria Rosa Esposta of San Severo, Foggia, dated 17 May 1832, highlighting the surname’s long-standing usage in ecclesiastical contexts.

Following the great waves of Italian emigration, the surname has spread to communities worldwide. In the United States and Argentina the name remains common among people of Italian descent, a testament to the enduring reach of the Italian diaspora and the retention of traditional family names.

In contemporary times, Esposito continues to be recognised far beyond Italian-speaking regions, partly due to its prominence in popular culture and the extensive genealogical records that trace its origins and proliferation across Europe and the Americas.
