Guarujá (; pronounced as /pt/) is a municipality in the São Paulo state of Brazil. It is part of the Metropolitan Region of Baixada Santista.[3] The population is 311,116 (2022 preliminary census count) in an area of 143.58km².[4] This place name comes from the Tupi language, and means "narrow path". The population is highly urbanized, forms a 2nd urban core and beachfront island across the river from São Vicente Island, the island (Ilha de Santo Amaro) is coterminous with the municipality, with exception of small offshore isles like Ilha dos Arvoredos.

Guarujá, its history, infrastructure and proximity to the country's most populous city, provides strong attractive real estate and tourism. Much of the region on the coast, the beaches near the center (mainly Asturias Pitangueiras, Enseada, and Tombo) are taken by buildings devoted to the seasonal population, who arrives mostly in summer.
