Quinceañero is the Spanish term commonly used for a boy celebrating a traditional 15th birthday.
The word is the masculine counterpart to quinceañera. Both terms derive from quince, meaning “fifteen,” and identify the young person connected with the milestone. In English-language discussions, quinceañera is often used more broadly for the celebration itself, so the masculine form may be less familiar.
Celebrations for boys are sometimes called quinceañeras in general conversation, but families may also use quinceañero or other regional expressions. There is no single worldwide format for a boy’s 15th-birthday event. Some families adapt familiar quinceañera elements, while others plan a different party or ceremony.
Quinceañero should not be confused with chambelán. A chambelán is a male escort or court member who supports the celebrant during the event. Padrino means godfather or sponsor and describes a supportive role, not necessarily the person whose birthday is being marked.
