The San Francisco River (Spanish: Río San Francisco) is a river that crosses the Bogotá savanna from east to west and is closely related to the history of the city.

It originates in the Páramo de Cruz Verde[1] and descends from the Monserrate hill.

In Avenida Jiménez with Sixth street, it converges underground with the San Agustín River.

[2] It was the largest river in the region and during its first centuries, it supplied the entire city with water, serving its course as the southern limit of the parish of Las Nieves.

[2][5] Between 1999 and 2001, the Environmental Axis was built, recovering a fragment of its original layout.
