What is the Spanish phrase for a quinceañera’s celebration of fifteen years?

The Spanish phrase for a quinceañera’s celebration of fifteen years is fiesta de quince años.

Literally, fiesta de quince años means “party of fifteen years.” It is a descriptive name for the celebration and is widely used alongside quinceañera. In some regions, families use quince años as a shorter version, while quinceañera can refer more directly to the girl who is turning 15.

Regional vocabulary is one reason English-language descriptions do not always use exactly the same label. Families may also describe the occasion simply as a birthday party, especially when the event is small or secular.

The phrase is not the name of a particular dance, religious service, or clothing style. Those features can appear within a celebration, but none is required by the phrase itself. Its defining reference is the fifteenth year of life.
