Lake Poinsett is a lake in Brevard County, Florida, United States, near Rockledge and Cocoa, with small portions in Orange County and Osceola County. It is the second-largest lake in Brevard County, after Lake Washington, though it is actually the smallest lake in Osceola County. It is the widest lake in Brevard County, with a distance of 5 miles (8 km) at its widest point. At the eastern portion of the lake, a channel connects the lake to Lake Florence and Barnett Lake.

Lake Poinsett and all the other lakes flow northward as part of the St. Johns River system.

It is where the Saint Johns River runs along county lines north of the lake. It is part of the St. Johns River Water Management District. At the extreme northwest corner of Lake Poinsett is Taylor Creek, a tributary of the St. Johns River.

The lake is named for Joel Roberts Poinsett, a diplomat who brought the poinsettia to the United States.
