Absaroka () was an area in the United States, comprising parts of the states of Montana, South Dakota, and Wyoming, that contemplated secession and statehood in 1939. Absaroka is from the Crow word meaning children of the large-beaked bird, also the namesake of the Absaroka mountain range. This region largely belongs to the Crow people and the Sioux, according to the Treaty of Fort Laramie (1851).
