The Tulare Formation is a Pliocene to Holocene epoch geologic formation in the central and southern San Joaquin Valley of central California.

It overlies the San Joaquin Formation, and can be up to 4,000 feet (1,200 m) thick.

Its sediments consist mainly of unconsolidated deposits of clay, silt, sand, and gravel.

Many freshwater fossils are preserved in the formation, dating back to the Neogene and Quaternary Periods of the Cenozoic Era. They include the largest fossil assemblage of clams and snails known on the Pacific Coast.
