Quinceañero is the Spanish term commonly used for the male counterpart of a quinceañera.
The word follows the same age-based formation as quinceañera, referring to a young man marking his fifteenth birthday. In English-language discussions, “quinceañero” is less familiar because the celebration has historically been associated more strongly with girls.
A quinceañero celebration may include several customs also found in quinceañeras, such as a formal reception, family participation, special clothing, music, and dancing. Practices differ considerably by country, family, religion, and community.
The term should not be confused with “chambelán,” which usually refers to a male attendant in the court of honor. A quinceañero is the honoree, while a chambelán is part of the supporting court.
