Praia do Pinho, Nudist beach in Santa Catarina, Brazil.

Praia do Pinho is a nudist beach in the state of Santa Catarina, located south of Florianópolis between wooded hills and the Atlantic Ocean. The beach is relatively small and naturally enclosed on both sides, giving it a sheltered feel away from busier coastal spots.

Naturism began at Praia do Pinho in the early 1980s, when practitioners clashed with other beachgoers and local residents. In 1984, the magazine Manchete published an article on naturism there, which sold out quickly and helped spread naturist ideas after Brazil's military regime ended. In 1988, the Brazilian Naturism Federation (FBrN) was founded on the beach by Celso Rossi.

This beach represents a space where visitors experience a lifestyle centered on freedom from clothing and natural acceptance of the human body. The community that gathers here has created its own social customs and values that differ markedly from conventional beach culture.

Access is via the Rodovia Interpraias, reached from a junction off the BR-101. The naturist stretch runs about 500 metres along the sand. To stay overnight at the beach, the Naturist Passport, also called the INF Card, is required.

In 1988 the Federação Brasileira de Naturismo was founded on the sand of Praia do Pinho, created by Celso Rossi from a merger of the Associação Brasileira de Naturismo. In January 2013 the beach hosted the first naturist surf championship in southern Brazil, and in 2007 it was the seat of the 6th Encontro Brasileiro de Naturismo.
