The male celebrant of a traditional fifteenth-birthday ceremony is called a quinceañero.
Quinceañero is the masculine Spanish counterpart of quinceañera. Both terms derive from quince, “fifteen,” and identify a young person reaching the traditional fifteenth-birthday milestone. The feminine form is much more internationally familiar because the celebration has historically centered on girls, but quinceañero is the standard masculine term.
A quinceañero celebration can borrow many of the same elements associated with a quinceañera, including formal clothing, a religious service, a reception, attendants, and choreographed dances. Families and communities may adapt the format to local expectations and the celebrant’s preferences.
The term is sometimes confused with chambelán, which refers to a male attendant or escort in a quinceañera court, not the birthday celebrant. Padrino means godfather or sponsor and describes a supporting role rather than the person whose fifteenth birthday is being marked.
