Lakeshore, formerly known as Fedhaven, is an unincorporated community in Polk County, Florida, United States. Lakeshore is located in eastern Polk County 1 mile (1.6 km) east of Nalcrest and 11 miles (18 km) east-southeast of Lake Wales. The community was established in the 1960s as a retirement community for former federal employees, and was thus named Fedhaven; when the land was later sold to private ownership, its name was changed to Lakeshore. Lakeshore has a post office with ZIP code 33854; Fedhaven and Lake Wales are both considered alternate addresses for the community. In 2004, three hurricanes severely damaged Lakeshore.
