デイド郡
Miami-Dade County, Florida (Dade County, until 1997); Dade County, Georgia; Dade County, Missouri; Dadeville, Alabama; and Dade City, Florida are all named after Major Dade. The now decommissioned fort on Egmont Key was also named for him. The battle is re-enacted at the Dade Battlefield Historic State Park each year. In 2002, the Dade County Courthouse was renamed the Major Francis Langhorne Dade County Courthouse by the Board of County Commissioners of Miami-Dade County. In the resolution changing the courthouse's name, the Board noted that it found "that Major Francis Langhorne Dade is a person who made a significant contribution to Miami-Dade County".
