The male counterpart of a quinceañera is called a quinceañero.
The Spanish noun quinceañera conventionally identifies a girl celebrating her fifteenth birthday, while quinceañero is the masculine counterpart. The distinction follows the gendered noun system of Spanish. In English-language discussions, however, quinceañera is sometimes used broadly for the celebration itself, even when families adapt the tradition for a boy.
The term should not be confused with chambelán. A chambelán is traditionally a male member of the honoree’s court of honor, not the male birthday celebrant. Likewise, padrino means godfather or sponsor and describes a family or ceremonial role rather than the person reaching the birthday milestone.
Quinceañero celebrations are less standardized in popular descriptions than quinceañeras, and family practices vary widely. Some boys’ celebrations use the same age milestone, while others use different names or formats. The core vocabulary therefore helps distinguish the honoree from the attendants and sponsors in a traditional event.
