Hialeah (/?ha???li??/) is a city in Miami-Dade County, Florida, United States. As of the 2010 census, Hialeah has a population of 224,669. Hialeah is the sixth-largest city in the state, and is a major city within the South Florida metropolitan area.
The city's name is most commonly attributed to Muskogee origin, "Haiyakpo" (prairie) and "hili" (pretty) combining in "Hialeah" to mean "pretty prairie". Alternatively, the word is of Seminole origin meaning "Upland Prairie". The city is located upon a large prairie between Biscayne Bay and the Everglades. The Seminole interpretation of its name, "High Prairie", evokes a picture of the grassy plains used by the native Indians coming from the everglades to dock their canoes and display their wares for the newcomers of Miami. This "high prairie" caught the eye of pioneer aviator Glenn Curtiss and Missouri cattleman James H. Bright in 1921. Together, they developed not only the town of Hialeah but also Hialeah Park Race Track.
