Sebastianus is Latin in Origin.

Sebastianus is the classical Latin form of a Greek-derived name, from Sebastianos, meaning "man of Sebaste" or "the venerable one." It ultimately stems from Greek sebastos, "venerable, august," related to sebas, "awe, reverence," and served as the Greek equivalent of Latin Augustus. In Roman usage Sebastianus could mark origin from cities named Sebaste (honorific foundations for Augustus) or function as a cognomen carrying a sense of reverence.

The cult of Saint Sebastian, a 3rd-century martyr, fixed Sebastianus in ecclesiastical Latin and propelled its spread across medieval and Renaissance Europe. Modern vernacular variants include Sebastian (English, German, Polish, Dutch, Scandinavian), Sébastien (French), Sebastián (Spanish), Sebastião (Portuguese), Sebastiano (Italian), Sebestyén (Hungarian), Sebastijan (Slovene/Croatian/Serbian). Short forms and diminutives: Bastian, Bastien, Seb, Seba. Feminine counterparts appear as Sebastiana, Sébastienne, and Sebastiana in Portuguese, Italian, and Spanish. Today the learned Sebastianus endures in liturgical, scholarly, and historical registers.
