Blue Cypress Lake, originally called Lake Wilmington, is a lake in Indian River County of the Treasure Coast in Florida. It is the largest lake in the Treasure Coast and Indian River County.

The lake is over 6,500 acres (26 km ²) in size, 21 mi (34 km) in circumference, and has an average depth of 8 feet (2 m). The lake is 2,100 acres (8.7 km ²) larger than Lake Washington, 27 mi (43 km) north of this lake.
