What is the name of the religious thanksgiving service often held for a quinceañera?

The religious thanksgiving service often held for a quinceañera is called a misa de acción de gracias.

The Spanish phrase means “Mass of thanksgiving.” In Catholic families, this service may take place before the reception and gives the celebrant an opportunity to express gratitude, receive a blessing, and participate in a public religious rite with family and friends. The exact ceremony depends on the parish and local custom.

A misa de acción de gracias is not identical to a wedding Mass, baptism, or Christmas Mass. Its purpose is connected to the fifteenth-birthday milestone. Some quinceañeras include a church service, while secular celebrations or non-Catholic families may omit it entirely.

Because quinceañera customs differ across countries and families, the service should be understood as a common tradition rather than a mandatory requirement. The broader celebration can include religious, cultural, and purely social elements in different combinations.
