Réveillon is the name of Brazil's New Year's Eve celebration, particularly the festivities on Rio de Janeiro's Copacabana Beach.
Brazilian Réveillon is celebrated with parties, music, fireworks, and gatherings that often continue through the night. Rio de Janeiro's Copacabana event is especially famous for its beach crowds and fireworks launched over the Atlantic Ocean.
Many participants wear white, a practice commonly associated with peace and good fortune. Some people also follow Afro-Brazilian religious traditions by making offerings to Iemanjá, a sea-associated deity, although customs vary by person, location, and religious community.
The Portuguese term Réveillon comes from French and is used in Brazil for the New Year's celebration and its festive meal or party. It should not be confused with Carnaval, Brazil's separate pre-Lenten festival, which usually takes place weeks later and has its own calendar and traditions.
