What Spanish name is commonly given to the young men in a quinceañera court?

The young men in a quinceañera court are commonly called chambelanes.

A chambelán is a male attendant who participates in the formal presentation and dances. The plural form, chambelanes, describes the group. In some regions and families, the attendants may instead be called acompañantes, caballeros, or another local term.

Traditionally, the court is paired with damas, the young women who accompany the quinceañera. A classic arrangement includes seven damas and seven chambelanes, although contemporary celebrations often change the size and composition of the group.

The word is sometimes confused with padrinos. Padrinos are sponsors or honored adults who may help provide ceremonial items or support the event; they are not simply another name for the young male attendants. Terminology varies across Spanish-speaking communities, so local usage can differ.
