The name "Okeechobee" comes from the Hitchiti words "oki" (water) and "chubi" (big). Mayaimi, meaning "big water," is the oldest known name, as reported in the 16th century, by Hernando de Escalante Fontaneda. Slightly later in the 16th century, René Goulaine de Laudonnière reported hearing about a large freshwater lake in southern Florida called "Serrope". By the 18th century the largely mythical lake was known to British mapmakers and chroniclers by the Spanish name "Laguna de Espiritu Santo." In the early 19th century it was known as "Mayacco Lake" or "Lake Mayaca" after the Mayaca people, originally from the upper reaches of the St. Johns River, who moved near the lake in the early 18th century. The modern Port Mayaca on the east side of the lake preserves that name.
