The traditional Spanish name for a boy celebrating his fifteenth birthday is quinceañero.
Quinceañero is the masculine counterpart to quinceañera. Both words are connected to quince, “fifteen,” and describe a fifteenth-birthday coming-of-age celebration or its participant, depending on context.
Quinceañera customs historically focused more often on girls, but boys may also have fifteenth-birthday celebrations. In some communities, a boy’s event is called a quinceañero, while families may adapt the format to include formal clothing, a court, dancing, a religious service, or a reception.
The term is sometimes confused with quince años, which is a broader phrase for the fifteenth-birthday tradition. Quinceañero specifically identifies the male celebrant or male form of the tradition. Usage varies by region, so the scale and rituals of a quinceañero are not identical everywhere.
