What is the Spanish name for the thanksgiving Mass traditionally held for a quinceañera?

The thanksgiving Mass traditionally associated with a quinceañera is called a Misa de Acción de Gracias.

The phrase literally means “Mass of Thanksgiving.” In Catholic families, it marks the religious dimension of the celebration and gives thanks for the quinceañera’s life and transition into a new stage. The Mass may take place before the reception, often with the celebrant wearing a formal dress and participating family members.

A quinceañera is not itself a Catholic sacrament. The Mass is a devotional or ceremonial service, so its form varies by parish, country, and family. Some celebrations are entirely secular, while others include a church service, a blessing, or a prayer ceremony.

The Mass should not be confused with Confirmation, which is a separate Catholic sacrament. Nor is every quinceañera required to include it; cultural practice and religious observance are often combined, but they are not identical.
