There are a total of 703 Latin boy names that have been compiled and organized in this comprehensive list. The selection includes classical Roman praenomina and nomina, saints’ names, medieval and ecclesiastical Latin forms, and verifiable historical attestations.

Latin boy names are personal names that originate in the Latin language and Roman naming traditions. They range from common praenomina (for example Marcus and Lucius) to family names and later ecclesiastical or medieval forms (for example Julius and Antonius). They often carry clear meanings tied to virtues, numbers, occupation, or physical traits and frequently keep classical endings like -us. They serve practical use in genealogy, literature, historical research, and modern naming.

Interesting and little-known facts about Latin boy names:
– The compiled list contains 703 validated entries drawn from classical texts, inscriptions, hagiographies, and scholarly name dictionaries.
– In ancient Rome, roughly a dozen praenomina were used most often, which led families to rely on nomina and cognomina for greater distinction.
– Tens of thousands of male names survive in epigraphic collections such as the Corpus Inscriptionum Latinarum and regional inscriptions.
– Many modern names (for example Adrian, Julian, Felix, Victor, Marcus) derive directly from Latin roots and remain common across languages.
– Masculine Latin names often end in -us in the nominative; modern forms frequently adapt or drop that ending (Marcus → Mark/Marco).
