Nasiopoulos Surname Meaning

The Greek surname Nasiopoulos (Νασιόπουλος) is a patronymic surname formed from the personal name Nasios (Νάσιος), a vernacular or shortened form likely derived from Athanasios (Αθανάσιος) through phonetic contraction. In Greek naming traditions, abbreviated forms of widely used baptismal names frequently became hereditary surnames. The suffix -opoulos (-όπουλος) developed during the Byzantine period and became especially common in the Peloponnese and southern mainland Greece, meaning “son of” or “descendant of.” This morphological structure indicates lineage through a male ancestor’s given name. Consequently, the surname Nasiopoulos signifies “son or descendant of Nasios.”
