A male celebrant of a traditional 15th-birthday event is called a quinceañero.
The term is the masculine counterpart to quinceañera. Both words are related to quince años, the Spanish expression associated with the age of fifteen. In English-language discussions, quinceañera is sometimes used broadly for the celebration even when the celebrant is male.
The celebration’s customs are not identical in every community. Some families use the same basic format for boys and girls, while others adapt the clothing, court, music, religious elements, or symbolic rituals. Contemporary celebrations may also avoid a strict gendered format altogether.
A quinceañero is not the same as a chambelán. A chambelán is traditionally a male attendant or escort in the celebrant’s court, whereas quinceañero identifies the person whose 15th birthday is being celebrated.
