What Spanish term describes the thanksgiving Mass sometimes held as part of a quinceañera?

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

The phrase translates literally as “Mass of thanksgiving.” In Catholic families, this service may take place before the reception and gives the honoree and her family an opportunity to express gratitude and receive a blessing. The service is often held in a parish church, although details vary widely.

A quinceañera is not itself a sacrament of the Catholic Church. It is a cultural celebration that may include Catholic elements, especially in communities where the tradition developed alongside Spanish and Latin American Catholic practice. Some families hold a religious service, while others choose a civil or entirely secular celebration.

The thanksgiving Mass should not be confused with a wedding Mass, baptism, or confirmation. Those are distinct Catholic rites or sacramental celebrations, whereas the quinceañera is a birthday and coming-of-age observance.
