The female sponsor or godmother at a quinceañera is commonly called a madrina.
Madrina means “godmother” or “female sponsor” in Spanish. At a quinceañera, a madrina may be a relative, family friend, or other trusted adult who supports the honoree and family. Depending on local custom, she may help provide a ceremonial item, contribute to expenses, or participate in a religious service.
The exact duties are not standardized. Some celebrations have multiple madrinas, each associated with a particular item such as the dress, cake, or accessories. Other families use the word in a more general sense for a principal female sponsor.
Madrina is different from dama, which usually refers to a girl or young woman in the court of honor. It is also different from chambelán, the commonly used term for a male escort. Spanish-speaking regions and individual families may apply these titles somewhat differently.
