The traditional Spanish term for the male counterpart of a quinceañera is “quinceañero.”
The word is formed from “quince,” meaning fifteen, and the masculine ending “-ero.” It describes a boy or young man celebrating his fifteenth birthday in a comparable tradition. The feminine form is “quinceañera,” with the ending “-era.”
Terminology is not perfectly uniform across Spanish-speaking regions. Many people use “quinceañera” as the familiar name for the broader tradition, even when discussing celebrations that are not exclusively for girls. Families may also describe a boy’s event simply as a fiesta de quince años or a fifteenth-birthday celebration.
The male form is less familiar in English-language popular culture because the quinceañera tradition has historically received more public attention as a girls’ rite of passage. That difference in visibility does not make “quinceañero” incorrect; it is the standard masculine Spanish noun for the celebrant.
