Lighthorse (or Light Horse) is an official or colloquial name for the police forces of federally recognized tribes in the United States. Some tribal governments officially refer to their police as Lighthorse while others do not. Historically, the term referred to the Five Civilized Tribes of the United States' mounted police forces. The Lighthorse were generally organized into companies and assigned to different districts. Perhaps the most famous were the Cherokee Lighthorsemen which had their origins in Georgia.
