The Pitt River Expedition is a series of expeditions in the U.S. state of California in the 1850s. The expeditions are named for the Pit River, one of many tributaries of the Sacramento River, and the Pitt River Indians (historical spellings differed). The expeditions were part of the larger American Indian Wars and took place during the California Gold Rush.
