The male form commonly used for a boy’s fifteenth-birthday celebration is quinceañero.
Quinceañero can refer to the male celebrant or, depending on context, the celebration itself. The feminine form quinceañera remains much more widely recognized because the tradition historically centered on a girl’s transition into young womanhood. Families and communities have increasingly adapted the custom for boys and for celebrations that do not follow a gendered format.
A quinceañero may include familiar elements such as a formal entrance, a religious service, a court, speeches, music, and a reception. None of these elements is mandatory everywhere. The exact program reflects family preference, local culture, religion, and the celebrant’s wishes.
The spelling preserves the ñ in Spanish. It should not be confused with quince, which means fifteen, or with quinceañista, a less standard form sometimes encountered in informal usage.
