The formal waltz at a quinceañera is commonly called a vals.
Vals is the Spanish word for “waltz,” a partnered dance in triple meter that became associated with formal celebrations in many Spanish-speaking communities. At a quinceañera, the honoree may perform a choreographed vals with family members, a court of honor, or both.
The dance is often one of the most rehearsed parts of the reception. Some families retain a slow, traditional ballroom style, while others combine waltz steps with contemporary choreography or popular music. There is no single universal routine, so the exact performance varies.
Vals is a dance name, not the name of the entire celebration. The broader event can be described as a quinceañera, quince años, or fiesta de quince años. Other dances may follow the formal vals during the reception, including regional or modern social dances.
