Piracicaba is a Brazilian municipality in the interior of the state of São Paulo, in the Southeast Region of the country. It is the main city of the Piracicaba Metropolitan Region (RMP) and is located about 150 km northwest of the state capital. It covers an area of just over 1,378 km², of which approximately 245 km² are urban area, with a population of 438,827 inhabitants, making it the 13th most populous municipality in the state.
It was founded in 1767, on the banks of the Piracicaba River, a water source that was vital for the region. During the 19th century, agriculture developed in the municipality, with a focus on the cultivation of sugarcane and coffee. However, in the first half of the 20th century the city fell into decline. With the end of the coffee cycle and the steady fall in sugar prices, the economy of Piracicaba stagnated, a situation that would only be reversed from the beginning of its industrialization onward.
