The masculine Spanish term for a boy celebrated at a quinceañera-style fifteenth birthday event is quinceañero.
Quinceañera is the feminine form associated with the traditional celebration for a girl, while quinceañero is the masculine form. In English-language usage, quinceañera is sometimes used broadly for the party itself, which can obscure the distinction between the honoree and the event.
Celebrations for boys are less standardized and may be called quinceañero celebrations or described simply as a boy’s fifteenth birthday. Their customs can differ from the established traditions associated with girls’ quinceañeras. Some families retain formal clothing, choreographed dances, a court, or a religious service; others create an entirely different party.
Spanish gendered nouns do not automatically indicate that every family follows a fixed ritual. Regional vocabulary and personal preference matter. The term quinceañero identifies the male celebrant, while fiesta de quince años identifies the broader fifteenth-birthday celebration.
