The Spanish noun traditionally identifying a boy celebrating his fifteenth birthday is quinceañero.
Quinceañero is the masculine counterpart of quinceañera, although the feminine tradition is much more widely recognized and documented. The word combines quince, meaning fifteen, with a suffix identifying a person associated with the milestone.
Usage is not completely uniform across Spanish-speaking communities. Families may use quince años for the event regardless of the celebrant’s gender, and local customs may differ in scale and ceremony. A boy’s celebration may include family gatherings, formal clothing, music, or religious elements without copying every customary feature of a girl’s quinceañera.
Quinceañero should not be confused with chambelán. A chambelán is a male member of a quinceañera court, while quinceañero identifies the celebrant.
