A quinceañera traditionally marks a girl’s 15th birthday.
The Spanish word quinceañera refers both to the celebrant and, commonly, to the coming-of-age celebration itself. The milestone is especially associated with Latin American communities and families of Latin American heritage. It is often compared with a sweet sixteen, although the traditions, symbolism, and religious elements are different.
A celebration may include a formal dress, a special entrance, a meal, music, dancing, and a religious service. Customs vary significantly by country, family, denomination, and community, so there is no single universal ceremony. In many Catholic families, the birthday is connected with a Mass of thanksgiving.
The number 15 is central to the tradition, but the event does not legally change a person’s age status. It is a cultural rite of passage rather than a legally defined ceremony. The male counterpart is often called a quinceañero.
