Jundiai is a city and municipality in the state of São Paulo in Brazil, situated 761 metres above sea level, some 60 km north of the city of São Paulo.
The municipality was founded on 14 December 1655, when it was elevated to the category of village, and it was first urbanised in 1657. Jundiai has borders with Várzea Paulista, Campo Limpo Paulista, Franco da Rocha, Cajamar, Pirapora do Bom Jesus, Cabreúva, Itupeva, Louveira, Vinhedo, Itatiba and Jarinu.
The city name originates from the Tupi language, meaning the place of the jundiá (‘fish with barbs’, the Rhamdia quelen species).
Jundiai has enjoyed a steep population growth over time, in large part fuelled by a shift of residents from the megalopolis of São Paulo, in search of better standards of living.
Grapes, coffee, timber, and grain are all produced in the area, and a grape festival is held each year in the city. In the past, Jundiai was considered the most important coffee producer of the region, primarily thanks to its exploitation of black slave labour. The most important industries of Jundiai are steel, textiles, wine, timber, cement, and porcelain, and tungsten is also mined nearby. Goods are shipped by rail to the port of Santos on the Atlantic Ocean.
Southeast of the city is the Serra do Japi, a 94-square kilometre state park and natural reserve containing one of the largest forested areas in the state of São Paulo, beautiful landscapes and many opportunities for eco-tourism, farming holidays and radical sports.
