Cerrado State Park, State park in Jaguariaíva, Paraná, Brazil.

Cerrado State Park covers 1,830.40 hectares in Jaguariaíva and Sengés, Paraná, protecting a stretch of the Jaguariaíva River canyon and the cerrado fields around it. Its terrain runs from 800 to 900 metres above sea level, dropping to about 750 metres in the canyon, and holds forest, cerrado, grassland and rocky outcrop vegetation. Trails total 3,000 metres, with a lookout over the canyon and a 40-metre waterfall on the Ribeirão Santo Antônio.

The park was created by decree 1.232 on 27 March 1992, covering 420.40 hectares in Jaguariaíva. On 2 October 2007 Governor Roberto Requião signed a decree expanding it to 1,830.40 hectares, adding parts of Sengés. The IAP closed it in 2010 for improvements and reopened it in November 2011 with new lookouts, trails and a visitor center.

The park represents a meeting point between two distinct plant zones, where visitors can observe how one ecosystem gradually transforms into another. Walking through the trails shows how the landscape shifts from grasslands to woodland in a natural transition.

The park entrance is 12 km from Jaguariaíva's municipal seat, in the Pesqueiro district, and the trails total 3,000 metres. Visits are open on Saturdays, Sundays and holidays; on Thursdays and Fridays entry must be booked in advance with the park coordination or the municipal tourism office. The overlook gives onto the Jaguariaíva River canyon, and a 40-metre waterfall lies on the Ribeirão Santo Antônio.

The area shelters a rare collection of ferns and related plants that scientists have documented here. Some of these species were first recorded in this region and are found in very few other locations.
