Which religion’s traditions are most commonly associated with the formal quinceañera Mass?

Roman Catholicism is the religion most commonly associated with the formal quinceañera Mass.

In Catholic families, the religious portion is often a misa de acción de gracias, or thanksgiving Mass. The service may include prayers, scripture readings, blessings, and participation by the honoree and her family. It is usually followed by a reception or party, although the exact order varies.

The tradition is especially visible in Latin American and Latino communities where Catholic practices have shaped family celebrations. However, a quinceañera is not exclusively Catholic. Protestant families, families of other faiths, and secular families may create their own ceremonies or hold only a reception.

The Mass does not make the event a sacrament, and it is not equivalent to baptism, confirmation, or marriage. It is a devotional celebration connected with a birthday and transition into a new life stage.
