Peanut Island is a 79-acre (320,000 m2) island at the mouth of the Lake Worth Inlet in Palm Beach County, Florida, United States. The island was created by dredging-related projects in 1918 which also created the inlet and the Port of Palm Beach.
Originally named Inlet Island, the island was renamed Peanut Island for a planned peanut oil-shipping operation which failed in 1946. A $13 million USD renovation on the island in 2005 resulted in Peanut Island Park including camp sites, a pier, and a manmade reef. The island also features a blast shelter built in secret for President John F. Kennedy shortly after his 1960 election. Kennedy often spent winters in nearby Palm Beach, Florida. The shelter is operated by the Palm Beach Maritime Museum and is open to visitors as an example of Cold War-era concerns for the president’s safety.
