The masculine Spanish term for a boy celebrating a similar fifteenth-birthday milestone is quinceañero.
Quinceañero is formed from the same quince años root as quinceañera, but it uses a masculine ending. The traditional quinceañera ceremony is most closely associated with girls, yet families and communities may organize comparable celebrations for boys. English-language usage often keeps the Spanish term when describing these events.
The term can also appear in contexts where a boy is part of a quinceañera celebration, so context matters. A male court attendant is more specifically a chambelán, while a sponsor may be called a padrino. Those words do not identify the birthday celebrant.
Contemporary celebrations show that customs are not fixed worldwide. Some families use a quinceañera-style format for any child, combine traditions, or create a secular event. The vocabulary reflects that broader adaptability while preserving the central connection to fifteen years.
