What Spanish term commonly names the formal celebration of a girl’s fifteenth birthday?

The formal celebration of a girl’s fifteenth birthday is commonly called a fiesta de quince años.

The phrase literally means “party of fifteen years” and is used in several Spanish-speaking regions. Quinceañera is also widely used, especially for the celebrant and for the event as a whole. Regional vocabulary is not completely uniform, so families may use quince, quince años, fiesta de quince, or quinceañera.

The celebration often combines a birthday party with coming-of-age symbolism. A formal entrance, ceremonial dances, a court of honor, special clothing, and a reception are common features, but none is mandatory everywhere.

English-language discussions sometimes treat quinceañera as the only name, yet fiesta de quince años is an important parallel expression. The exact wording can reflect country, family background, and whether the speaker means the person or the celebration.
