Quinceañero is a Spanish term for a boy celebrating a comparable fifteenth birthday.
The term is the masculine counterpart of quinceañera and uses the same quince, or fifteen, root. In some Spanish-speaking communities, families organize a quinceañero with a formal party, special clothing, a church service, music, and a ceremonial dance. The details depend on local custom and family preference.
Quinceañera traditions historically centered much more strongly on girls, so quinceañero celebrations are less uniform and less widely standardized. Some boys instead celebrate a fifteenth birthday with an ordinary party, while others adapt familiar quinceañera elements.
The word should not be confused with chambelán, which may refer to a male member of a quinceañera court, or padrino, which means sponsor. Quinceañero identifies the celebrant, not a participant supporting someone else’s event.
