Mananciais de Campos do Jordão State Park, State park in São Paulo, Brazil.

Mananciais de Campos do Jordão State Park is a protected forest area at high altitude in São Paulo state, consisting of elevated Atlantic Forest and native pine woodland. The region contains extensive green areas with a reservoir that also serves as an important water source for the surrounding municipality.

The park was created by state decree 37.539 on 27 September 1993, uniting two state-owned parcels bought in the 1940s during the Prefeitura Sanitária de Campos do Jordão. Its aim was to stop urban expansion from occupying the land and to protect the water sources feeding the Salto Dam, built in 1940 at the confluence of the Córrego do Coutinho and Ribeirão das Perdizes. Since 2006 it has formed part of the Mantiqueira Mosaic of conservation units.

The park's name refers to the water sources it protects: the streams that feed the Salto Dam, built in 1940 where the Córrego do Coutinho and Ribeirão das Perdizes meet. The dam supplies much of Campos do Jordão's water, and the surrounding pine stands and secondary forest grew around it.

The area is accessible by hiking trails that run through different forest types and offer varying difficulty levels. Visitors should wear good footwear and be prepared for changeable weather at high altitude.

The Salto Dam, built in 1940 where the Córrego do Coutinho and Ribeirão das Perdizes meet, supplies up to 30% of Campos do Jordão's water; the park was created in 1993 to shield its catchment from the city's expanding urban area.
