Firmin is Latin in Origin.

Firmin is a French masculine given name from the Late Latin Firminus, built on firmus, “steadfast, stable, strong.” It began as a Roman cognomen and migrated into Christian onomastics, carrying the sense of reliability and firmness.

Its spread owes much to saintly cults, especially Saint Firmin of Amiens (3rd–4th century), whose veneration travelled into Navarre and underlies Pamplona’s famed San Fermín festival. The name flourished in medieval and early modern France and today reads as vintage but accessible; in English it is rare yet recognizable through figures like typographer Ambroise Firmin-Didot and literary uses (e.g., Sam Savage’s novel Firmin). Variants include Spanish Fermín (Basque Fermin), Portuguese and Italian Firmino/Fermino, and the learned form Firminus; related surnames appear across Romance languages. Feminine counterparts are Firmina (Portuguese) and Fermina (Spanish). Meaning summary: “the steadfast, firm one.”
