What is the Spanish name often used for a quinceañera’s formal thanksgiving Mass?

The Spanish name often used for a quinceañera’s formal thanksgiving Mass is Misa de acción de gracias.

The phrase translates as “thanksgiving Mass.” It describes a Catholic service in which the celebrant and family give thanks and ask for blessings as the young person reaches 15. The Mass may take place before the reception and can include family members, sponsors, and the court of honor.

The service is particularly associated with quinceañera customs in Mexico and other Latin American communities. Depending on local practice, the celebrant may carry or receive a Bible, rosary, medal, or bouquet, and may be presented before the congregation.

The Mass should not be treated as a universal requirement. Many families celebrate without a church service, and Catholic parishes may have their own rules about preparation and participation. The phrase identifies the religious service, not the entire birthday party.
