Carnival of Brazil is an annual Brazilian festival held between the Friday afternoon (51 days before Easter) and Ash Wednesday at noon, which marks the beginning of Lent, the forty-day period before Easter.

Rhythm, participation, and costumes vary from one region of Brazil to another. In the southeastern cities of Rio de Janeiro, São Paulo, and Vitória, huge organized parades are led by samba schools. Those official parades are meant to be watched by the public, while minor parades ("blocos") allowing public participation can be found in other cities, like Belo Horizonte, also in the southeastern region. The northeastern cities of Recife, Olinda, Salvador, and Porto Seguro have organized groups parading through streets, and public interacts directly with them. This carnival is also influenced by African-Brazilian culture. It is a six-day party where crowds follow the trios elétricos through the city streets, dancing and singing. Also in northeast, Olinda carnival features unique characteristics, heavily influenced by local folklore and cultural manifestations, such as Frevo and Maracatu.
