The Cherokee Nation was a legal, autonomous, tribal government in North America recognized from 1794 to 1907. It was often referred to simply as "The Nation" by its inhabitants. The government was effectively disbanded in 1907, after its land rights had been extinguished, prior to the admission of Oklahoma as a state. During the late 20th century, the Cherokee people reorganized, instituting a government with sovereign jurisdiction known as the Cherokee Nation. On July 9, 2020, the United States Supreme Court ruled that the Muscogee (Creek) Nation had never been disestablished in the years before allotment and Oklahoma Statehood.

The Cherokee Nation, formerly known as the Cherokee Nation of Oklahoma, is the largest of three federally recognized tribes of Cherokees in the United States. It includes people descended from members of the Old Cherokee Nation who relocated, due to increasing pressure, from the Southeast to Indian Territory and Cherokees who were forced to relocate on the Trail of Tears. The tribe also includes descendants of Cherokee Freedmen, Absentee Shawnee, and Natchez Nation. As of 2023, over 450,000 people were enrolled in the Cherokee Nation.
