What is the traditional Catholic church service associated with a quinceañera called?

The traditional Catholic church service associated with a quinceañera is called a misa de acción de gracias.

This Spanish phrase means “Mass of thanksgiving.” It gives the celebrant and family an opportunity to express gratitude for the young person’s life and to seek blessing and guidance. The service is commonly held before the reception when the family follows Catholic practice.

A quinceañera Mass is not the same sacrament as a wedding. The celebrant is not marrying, and participation does not itself create a legal status. Catholic parishes may set their own requirements, such as preparation classes, baptismal records, or involvement in parish life.

Not every quinceañera includes a Mass. Families may be Protestant, follow another faith, be nonreligious, or choose a civil celebration. The Spanish title is therefore a traditional Catholic term rather than a compulsory part of every modern event.
