The traditional male attendant at a quinceañera is called a chambelán.
A chambelán is part of the celebrant’s court, a group of relatives or friends who participate in the formal presentation and choreographed dances. The term is associated with the French-derived Spanish word chambelán, historically connected with a chamberlain or court attendant.
Depending on the region, families may use other names for male members of the court, including escorts or damas y chambelanes for the group as a whole. The exact roles are not universal. Some modern celebrations have no court, use mixed-gender attendants, or replace formal titles with informal ones.
A chambelán is not the same thing as a padrino. Padrinos are sponsors or honored adult supporters, while chambelanes are usually young attendants who participate in the event’s presentation and dance program.
