What is the religious thanksgiving ceremony often associated with a quinceañera called?

The religious thanksgiving ceremony often associated with a quinceañera is called a Misa de Acción de Gracias.

This Spanish phrase means “Thanksgiving Mass.” In Catholic families, it may be held before the reception and gives the celebrant an opportunity to give thanks for her life, family, and continued growth. A priest may offer a blessing, and family members or attendants can participate.

The religious service is not required for every quinceañera. Some celebrations are secular, while others take place in a different Christian denomination or another faith tradition. The reception and ceremonial customs can therefore exist independently of a Catholic Mass.

Misa de Acción de Gracias should not be confused with a wedding Mass. A quinceañera is a birthday and coming-of-age celebration, not a marriage ceremony, even when it is held in a church and includes formal processions.
