The Calaveras River is a river in the San Joaquin Valley of California.

It flows roughly southwest for 51.9 miles (83.5 km) from the confluence of its north and south forks in Calaveras County to its confluence with the San Joaquin River in the city of Stockton.

In the past, it has been used for agriculture and irrigation, drinking water, and for recreational purposes. There have been many improvement projects on the Calaveras River to address its pollution and efficiency for local residents.
