A male sponsor or godfather at a quinceañera is commonly called a padrino.
Padrino is the masculine Spanish term for godfather or sponsor. In a quinceañera context, a padrino may help support the event or sponsor a particular item, depending on the family’s traditions and arrangements.
The role is different from that of a chambelán. A chambelán is normally a young male attendant in the court of honor, while a padrino is a sponsor or godparent figure. One person could potentially have more than one relationship to the celebration, but the terms describe different roles.
Padrino is not a mandatory title in every quinceañera. Secular celebrations may use sponsor language informally, while religious families may connect the role more closely with godparent traditions.
