Quinceañero is the usual Spanish term for a boy celebrating his fifteenth birthday in a quinceañera tradition.
The masculine noun corresponds to quinceañera, the term commonly used for a girl. Both words are connected with quince, the Spanish word for fifteen, and are associated with the age-based coming-of-age celebration.
Although quinceañera is much more widely recognized, boys can also have comparable fifteenth-birthday celebrations. In some communities, families use quinceañero for the celebrant, while the event itself may be described with a masculine form or simply as a fifteenth-birthday celebration.
Terminology varies across Spanish-speaking regions and families. The word should not be confused with chambelán, which generally refers to a male member of the celebrant’s court rather than the birthday celebrant himself.
