What is the male equivalent of a quinceañera commonly called?

The male equivalent of a quinceañera is commonly called a quinceañero.

Quinceañero is the masculine Spanish form related to quinceañera. It can describe a boy celebrating his fifteenth birthday in a similar coming-of-age tradition. Although quinceañeras for girls are more widely recognized internationally, some families and communities adapt the ceremony for boys.

The celebration is not governed by one universal rulebook. A quinceañero may have a formal reception, attendants, special clothing, a religious service, or symbolic rituals modeled on local quinceañera customs. Other families may choose an entirely different type of fifteenth-birthday event.

The terms are sometimes confused with padrino, which means a sponsor or godfather, and chambelán, which can refer to a male attendant. Neither word means the male celebrant. Quinceañero specifically identifies the person reaching the fifteenth-birthday milestone.
