Juiz de Fora (, Outsider Judge), also known as J.F., is a city in the southeastern Brazilian state of Minas Gerais, approximately from the state border with Rio de Janeiro. According to 2020 estimates the current population is about 573,285 inhabitants. The geographical area of the municipality is . The city's location was a key factor in its economic and demographic development since it is situated between the three most important financial and economic metropolises of southeast Brazil (and also the three largest urban sprawls of the country): Rio de Janeiro (), Belo Horizonte () and São Paulo (). Major highways connect Juiz de Fora with these three metropolitan areas, the most important being the BR 040 which connects Brasília with Rio de Janeiro via Belo Horizonte. The city is built on the Paraibuna, a major tributary of the Paraíba do Sul river.

The region was covered with dense forest (hence its name; "Zona da Mata", Forest Zone). Despite the opening of the new route the area remained largely uninhabited and most of its scarce settlement was centered on the road itself. The first permanent inhabitants of the municipality were merchants and farmers who supplied the travelers' needs on the long road between the coast and the gold region. Further development would only take place after the decline of gold mining in the central zone of Minas Gerais. The capital previously invested in the mines was now invested in coffee plantations, and the region of Zona da Mata became a fertile ground to invest in. The position of the village then called Santo Antônio do Paraibuna was favourable due to the road connection with the capital of the country and its harbour. In 1850 the small village was officially elevated to city status. Progress continued in 1861 with the completion of the first macadamized road in Latin America, the Estrada União e Indústria (Union and Industry), replacing the Caminho Novo. Its name reflected the newfound wealth of the city, for industry replaced coffee-related agriculture as its economic heart. Five years later a new railway, the Estrada de Ferro Dom Pedro II, reached the city and
