Vallecito (Spanish for "Little Valley") is a census-designated place (CDP) in Calaveras County, California, United States.

[3] Nearby is Moaning Cavern, the largest cave chamber in California, which the Miwok Indians used as a burial ground.

The Vallecito Bell, cast at Troy, New York in 1853, was brought around Cape Horn.

It was purchased from the ship with funds contributed by early-day residents and brought to Vallecito to be erected in a large oak tree in 1854.

It was used to call the people together until February 16, 1939, when a severe wind blew the old tree down.

The first post office opened in 1854 as Vallicita; the town's name was changed to Vallecito in 1940.
