Tuckahoe, Historic mansion in Jensen Beach, United States.

Tuckahoe, also called the Leach Mansion, is a 1938 house at 1921 North East Indian River Drive in Jensen Beach, inside Indian RiverSide Park and atop the Mount Elizabeth Archeological Site. The Sisters of St. Joseph added two dormitory wings in 1950; a 2009 rehabilitation by architect Bert Bender of Key West added a catering kitchen, banquet room, terraces and an amphitheater.

Tuckahoe was built in 1938 for Willaford Ransom Leach and his wife Anne Winship Bates Leach on about 54 acres of riverfront land. The Leaches sold it in 1950 to the Sisters of St. Joseph of St. Augustine, who added two dormitory wings and moved their novitiate and Saint Joseph College of Florida there. The college closed in May 1972 and the campus passed to Florida Institute of Technology, which used the mansion as its administration building until closing its Jensen Beach campus in 1986. Martin County acquired the property in 1997 and completed its rehabilitation in 2009.

The property sits atop the Mount Elizabeth Archaeological Site, where Native American communities left pottery, tools, and shell ornaments behind. These artifacts span thousands of years and show how long people have lived in this area.

The property works well for large events and gatherings because of its rooms and outdoor spaces with room for different activities. Visitors should know this is mainly an events venue and access is best arranged through scheduled occasions.

Tuckahoe sits on the Mount Elizabeth Archeological Site, added to the National Register of Historic Places on September 14, 2002, three years before the mansion itself was listed on November 30, 2005. On November 4, 2010, the Halpatiokee Chapter Daughters of the American Revolution placed a plaque on the building.
