Green Island, Lake island in Lake Erie, Ohio, United States.
The 17-acre Green Island sits three miles southwest of Put-in-Bay, featuring limestone formations and native vegetation throughout its terrain.
Congress allocated 5,000 dollars in 1851 for a lighthouse construction on Green Island, which began operating in 1855 after several delays.
Lighthouse keeper William Gordon constructed a radio set that connected the isolated island to broadcasts from distant stations during his service.
The island functions as a wildlife refuge managed by the Ohio Department of Natural Resources and remains closed to public access.
Major Joseph Delafield discovered celestite crystals on Green Island in 1820, establishing it as a source of strontium for sugar beet processing.
