Quinceañero is the Spanish term commonly used for a boy celebrating a male version of a quinceañera.
The word follows the masculine form of the Spanish noun. It is connected to quince años, meaning “fifteen years,” and refers to a fifteenth-birthday celebration for a boy.
Terminology varies widely. Some families use quinceañera for the broader tradition regardless of gender, while others choose quinceañero, quince años, or a completely different phrase. The events themselves may include formal clothing, a religious service, a court, family dances, and a reception.
Quinceañero should not be confused with quincena or quincenal. Those Spanish words relate to a fifteen-day period or something occurring every two weeks, not to a fifteenth-birthday celebration.
