Serra do Papagaio State Park, State park in the Mantiqueira Mountains, Minas Gerais, Brazil.

Serra do Papagaio State Park covers 22,917 hectares across Aiuruoca, Alagoa, Baependi, Itamonte and Pouso Alto in Minas Gerais. It lies in the Mantiqueira Mountains and includes parts of the Garrafão and Papagaio ranges. About half the park has slopes steeper than 1,800 metres, with Morro da Mitra do Bispo reaching 2,149 metres and Pico do Bandeira 2,357 metres.

The protected area was officially established in 1998 through a government decree and later became part of a larger network of conservation areas. This integration helped secure the region as an important natural reserve.

The park lies within the Mantiqueira Mosaic of conservation units, created in 2006. Its name comes from the Papagaio range, one of the two mountain chains it protects. Nearby, in the same chain as Pico do Papagaio, is a spot called Retiro dos Pedros.

The area has several entry points scattered across different municipalities, each offering different access routes. It helps to check which entry point is closest to where you want to go before visiting.

The park protects the headwaters of rivers that form the Rio Grande, and it borders Itatiaia National Park to the south, forming a continuous protected mountain area. A proposed small hydroelectric plant in Aiuruoca, part of a programme of 65 such plants in Brazil, drew protests from local residents and environmentalists.
