Quinceañero is the common Spanish term for a boy or young man celebrating a male quinceañera milestone.
The masculine form changes the ending of quinceañera: quinceañero refers to the celebrant, while quinceañera conventionally refers to the girl or young woman and, by extension, the celebration. In English, quinceañera is also widely used as the name of the event itself, even when the focus is not on the participant’s grammatical gender.
Male versions of the celebration are less standardized across communities than the traditional quinceañera. Families may adapt the ceremony, court, clothing, music, and religious elements according to local custom. Some communities use quinceañero for the celebrant, while others describe the event in broader terms such as a fifteenth-birthday celebration.
Quinceañero should not be confused with chambelán. A chambelán is a male attendant in a court; a quinceañero is the male celebrant himself.
