What are the male escorts in a traditional quinceañera court called?

The male escorts in a traditional quinceañera court are called chambelanes.

Chambelanes accompany the quinceañera during formal portions of the celebration, including the entrance, photographs, and choreographed waltz. The word is used especially in Mexican and Mexican-American contexts, though other regions may use different terms such as escortes or court members.

A court commonly pairs chambelanes with damas, the female attendants. The number of participants is flexible, and contemporary celebrations may include friends or relatives without following a fixed gender arrangement.

Chambelanes are not the same as padrinos. Padrinos are sponsors or godparents who may help support specific elements of the event. Chambelanes are members of the ceremonial court and usually have a performance or escorting role.
