Piracicaba (Portuguese pronunciation: [piɾɐsiˈkabɐ] or [piˌɾasiˈkabɐ]) is a city located in the Brazilian state of São Paulo.

[3] The name refers to the waterfalls of the Piracicaba River, which bisects the city, which is a point where the "piracema"—fish swimming upstream to reproduce— are stopped.

[4] In 1766, Antonio Correa Barbosa, charged with the task of establishing a settlement on the estuary of Piracicaba river, opted for a location about 90 kilometres (56 mi) from it.

In 1856, Vila Nova da Constituição was promoted to city status and in 1877 it was officially named "Piracicaba", following a law by the then councilman and future Brazilian president Prudente de Morais.

[10] Piracicaba is known by the nickname "Noiva da Colina",[11] meaning "Bride of the Hill", and is the annual host to the "Festa das Nações" (Nations' Party, where people may find foods from all over the world),[12] and to the "Salão Internacional do Humor" (International Humor Exhibition), where cartoonists from around the world display comic drawings.

[19] Copersucar, a large company that has a center of research on genetic improvement of sugarcane, participates in this growing industry.

[20][21] Another characteristic economic feature is the presence of large industries, the main ones being Caterpillar,[22] ArcelorMittal,[23] Raizen and Hyundai.

According to data from the 2019 Census conducted by the IBGE, the population of Piracicaba was composed that year by Catholics (59.78%), Evangelicals (27.42%), no religious affiliation (7.47%), Spiritist (2.9%) and Jehovah's Witnesses (0.95%).

The company is currently an operator of cell phones, fixed lines, internet (fiber optics/4G) and television (satellite and cable).
