What Spanish phrase names the quinceañera’s customary fifteenth-birthday party?

The customary fifteenth-birthday party is called a fiesta de quince años.

The phrase means “party of fifteen years” and is one of the standard Spanish names for the celebration. Quinceañera is another widely used term, especially when referring to the celebrant herself. In English, quinceañera commonly serves as the name for both the young woman and the event.

A fiesta de quince años may include a church service, a formal entrance, a court of honor, a special dance, dinner, music, and a cake. None of those elements is universal, however. Families select traditions according to region, religion, finances, and personal taste.

The event is a cultural coming-of-age celebration rather than a single standardized ceremony. A large formal reception and a modest family gathering can both be described as a fiesta de quince años if they mark the fifteenth birthday.
