The masculine Spanish equivalent of quinceañera for a boy celebrating his 15th birthday is quinceañero.
Quinceañera is the feminine term connected with quince años, meaning “fifteen years,” while quinceañero is the masculine form. The vocabulary reflects Spanish grammatical gender rather than a different number of years.
In many communities, the quinceañera tradition is historically associated more strongly with girls, particularly because of its presentation and transition symbolism. However, boys may also have fifteenth-birthday celebrations, and some families adapt the customs for a quinceañero.
Usage is not perfectly uniform across all Spanish-speaking regions. Families may use local terms such as fiesta de quince años or simply describe the event as a fifteenth birthday celebration. Quinceañero is the standard masculine counterpart in general Spanish usage.
