Yannopoulos Surname Meaning

The Greek surname Yannopoulos (Γιαννόπουλος) is a patronymic surname derived from Giannis (Γιάννης), the familiar form of Ioannis (Ιωάννης), meaning “God is gracious.” The suffix -opoulos (-όπουλος) is a patronymic marker meaning “son of” or “descendant of,” particularly common in southern Greek naming traditions. In traditional Greek communities, familiar spoken forms of baptismal names frequently became hereditary surnames when recorded in church registers and later civil documentation. Over time, the patronymic structure remained stable across generations. Consequently, the surname Yannopoulos signifies “the son of Giannis,” reflecting patronymic lineage rooted in religious naming tradition rather than occupation.
