What Spanish name is commonly given to the religious thanksgiving Mass associated with a quinceañera?

The religious thanksgiving Mass associated with a quinceañera is commonly called a misa de acción de gracias.

The phrase means “Mass of thanksgiving.” In Catholic families, the service may take place before the reception and gives the honoree an opportunity to express gratitude, receive a blessing, and be accompanied by relatives and friends.

The service is not a sacrament equivalent to marriage or baptism. It is a thanksgiving liturgy, and its details can differ by parish, country, and family. Some celebrations include readings, prayers, or a presentation of symbolic objects.

Not every quinceañera includes a Mass. Secular parties are common, and families from other Christian traditions or other faiths may use different ceremonies. The Spanish phrase therefore identifies a traditional Catholic element, not a compulsory feature of the birthday celebration.
