The Mayaimi (also Maymi, Maimi) were a Native American people who lived around Lake Okeechobee (the Belle Glade culture area) in Florida from the beginning of the Common Era until the 17th or 18th century. The group took their name from the lake, which was then called Mayaimi, which meant "big water" in the language of the Mayaimi, Calusa, and Tequesta tribes. The origin of the language has not been determined, as the meanings of only ten words were recorded before extinction. The current name of Okeechobee for the lake is derived from the Hitchiti word meaning "big water". The Mayaimis have no linguistic or cultural relationship with the Miamis of Great Lakes region.
