Big Mound City (8PB48) is a prehistoric site near Canal Point, Florida, United States.

It is located 10 miles east of Canal Point, off U.S. Route 98.

Big Mound City is the site of one of four recognized monumental Native American earthworks built in the Lake Okeechobee Basin area of southeastern Florida.

[2] Dating from the Glades period III (circa 1000 AD), it is a combination of at least nine mound structures and a ridge complex, including radiating causeways and crescent-shaped man-made ponds.

[5][6][7] Researchers of mound-building cultures in Florida such as Jerald Milanich believe that the same Indians who built Big Mound City also built Tony's Mound, Fort Center and the Ortona Prehistoric Village, all in the Lake Okeechobee Basin area.
