The English-language name commonly used for the fiesta de quince años celebration is quinceañera.
Quinceañera is a Spanish loanword that is widely used in English, especially in the United States. In Spanish, it can refer to the girl who reaches fifteen and, by extension, to the celebration held for her. Fiesta de quince años more explicitly names the party itself.
The event is a Latin American coming-of-age tradition centered on a girl’s fifteenth birthday. Common elements may include a formal dress, a court, a religious service, a waltz, speeches, and a reception, although no single checklist applies everywhere.
It is often compared with a sweet sixteen party, but the traditions are not identical. A quinceañera has its own Spanish terminology, historical development, and ceremonial customs.
