The São Francisco River, known in English as the San Francisco River, is a large river in Brazil. With a length of 2,914 kilometres (1,811 mi), it is the longest river that runs entirely in Brazilian territory, and the fourth longest in South America and overall in Brazil. It is also locally known as the Velho Chico, and was once known as the Opara by the Indigenous people before colonization.
