The State of Sequoyah was a proposed state to be established from the Indian Territory in the eastern part of present-day Oklahoma.
 In 1905, with the end of tribal governments looming (as prescribed by the Curtis Act of 1898), Native Americans of the Five Civilized Tribes—the Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole—in Indian Territory proposed to create a state as a means to retain control of their lands.
 Their intention was to have a state under Native American constitution and governance.
 The proposed state was to be named in honor of Sequoyah, the Cherokee who created a writing system in 1825 for the Cherokee language.

The term "Five Civilized Tribes" derives from the colonial and early federal period in the history of the United States.
 It refers to five Native American nations—the Cherokee, Chickasaw, Choctaw, Creek (Muscogee), and Seminole.
 These are the first five tribes that Anglo-European settlers generally considered to be "civilized" according to their own worldview, because these five tribes adopted attributes of the colonists' culture, for example, Christianity, centralized governments, literacy, market participation, written constitutions, intermarriage with white Americans, and plantation slavery practices.
 The Five Civilized Tribes tended to maintain stable political relations with the Europeans.
