Quinceañero is the male Spanish term corresponding to quinceañera for a boy’s fifteenth-birthday celebration.
The word uses the masculine Spanish ending -o, while quinceañera uses the feminine ending -a. Both terms are built from quince, meaning fifteen, and refer to a young person associated with a fifteenth-birthday coming-of-age celebration.
Quinceañero celebrations are less standardized and less widespread than the traditional quinceañera in many communities. Some families adapt familiar elements such as formal attire, a court, a religious service, speeches, dancing, or a reception, while others create a completely different event.
Quinceañero should not be confused with padrino, which means a sponsor or godfather, or chambelán, which can refer to a male escort or attendant. Those words describe roles in a celebration, not the birthday celebrant himself.
