Jensen Beach is an unincorporated community and census-designated place (CDP) in Martin County, Florida, United States. The population was 12,652 at the 2020 census. It is part of the Port St. Lucie, Florida Metropolitan Statistical Area. History The history of Jensen Beach in the 19th century revolved around pineapple farming. John Laurence Jensen, an immigrant from Denmark, arrived in 1881, and set up his pineapple plantation, which became the town of Jensen. By 1894, the Florida East Coast Railway reached Jensen Beach, and freight shipments were loaded directly onto the freight cars. By 1895, Jensen was called the "Pineapple Capital of the World", shipping over one million boxes of pineapples each year during the June and July season. To help handle the increased pineapple production, a pineapple factory was built, but a hard freeze in 1895 devastated most of the small pineapple plantations. Two fires, in 1908 and 1910, destroyed most of Jensen Beach and its remaining pineapple farms. The industry finally collapsed in 1920 due to a wide variety of financial and agriculture problems. Growers decided to turn their efforts in another direction: raising citrus fruits. The pineapple has become a symbol of Jensen Beach. The fruit legacy is celebrated annually during the Jensen Beach Pineapple Festival. Jensen Beach was incorporated as "Jensen" in 1926 during the Florida Land Boom, but was dissolved seven years later by the State of Florida in 1933 following the onset of the Great Depression. The town's name was officially changed to "Jensen Beach" by Martin County in 1943. In the second half of the 1900s, Saint Joseph College of Florida and later the Florida Institute of Technology both located on the Mansion at Tuckahoe premises in Jensen Beach.
