Serra Nova State Park, State park in Minas Gerais, Brazil

Serra Nova State Park covers 49,830 hectares across Rio Pardo de Minas, Porteirinha, Mato Verde, Riacho dos Machados and Serranópolis de Minas, 640 km from Belo Horizonte. It spans parts of the Serra Geral and Espinhaço mountains on the divide between the São Francisco and Jequitinhonha basins. The Mosquito River cuts through the Serra do Talhado, and springs feed the São Gonçalo stream and the Ventania, Suçuarana, Bomba, Ladim and Córrego da Velha rivers.

The protected area was established in 2003 with initial boundaries, then expanded several years later to encompass additional natural habitats. These changes reflected growing efforts to safeguard the region's ecological importance.

The park's name links two serras: the original Serra Nova and the Serra do Talhado, added in the 2008 expansion proposal that also gave the park its alternate name, Parque Estadual Serra Nova e Talhado. The Mosquito River cuts through the Serra do Talhado, and springs within the park feed the São Gonçalo stream and the Ventania, Suçuarana, Bomba, Ladim and Córrego da Velha rivers.

As of 2017 the park admitted visitors daily from 8:00 to 17:00. Sound recordings, climbing, abseiling, ziplining, domestic animals, fires and camping are prohibited. Stay on marked trails, preferably with a local guide, and leave watercourses at the first sign of rain.

Scientists discovered multiple amphibian species here in 2007, including one that had never been documented before. This finding revealed how much remained unknown about the biodiversity of these remote mountain areas.
