Pico do Jabre State Park, State park in Paraíba, Brazil.

Pico do Jabre State Park protects the highest peak in northeast Brazil, rising to 1,197 metres in the Serra do Teixeira. Created in 1992, it covers about 500 hectares, mostly in Matureia, with terrain between 750 and 1,000 metres. Its montane forest mixes Atlantic Forest and caatinga species such as angico, aroeira and quixabeira.

Brothers Antônio and Francisco Pereira Monteiro climbed the Serra do Teixeira in 1761 seeking escaped slaves; they found none but claimed the unoccupied land, building improvements and obtaining a grant named Data de Santo Antônio. The park itself was created by state decree 14.843 of 19 October 1992, with about 500 hectares, and is administered by Sudema. In April 2016 the public prosecutor's office sued mobile operators Tim, Oi and Embratel and 24 property owners over illegal construction in the permanent preservation area.

The park serves as a working research area where botanists study and protect plant species found nowhere else in the region. Local guides and researchers help visitors understand why these mountain ecosystems matter for preserving northeastern Brazil's natural heritage.

The park lies in the municipalities of Matureia and Mãe d'Água, most of it in Matureia, with terrain between 750 and 1,000 m. Rain falls mostly from February to May, when trails and dirt access roads get muddy. Bring sturdy footwear and check conditions with Sudema, the state agency that administers the park, before setting out.

The park protects the only example of montane forest in the Atlantic Forest domain of Paraíba, where humid forest species grow alongside caatinga elements. Botanists studied new or rare Acanthaceae and Bromeliaceae here in the 1990s and 2000s. Dew and groundwater, not rainfall alone, keep the vegetation alive.
