Poinciana is a settlement and census-designated place (CDP) in Osceola and Polk counties in the U.S. state of Florida. It lies southwest of Kissimmee and about 14 miles (23km) east of Haines City. As of the 2010 United States Census, the CDP had a population of 53,193. As of April 2012 the population of the 10 Villages which make up the Association of Poinciana Villages (APV), which covers a wider area than the CDP, was reported as 69,857. According to the latest census reports the adjoining tracts outside the CDP represent an additional 29,914 persons. Depending on the definition, the greater Poinciana Area represents a population of between 53,193 and 83,107. This puts Poinciana as one of the fastest growth areas for Central Florida over the past decade. US Highway 17/92 (here part of the Orange Blossom Trail) runs through the north of Poinciana. Local bus service is provided to Kissimmee and Haines City by the Lynx network. Poinciana is planned to be the southern terminus of the proposed SunRail system. Work is also supposed to begin shortly on a toll road to connect Poinciana more directly to Interstate 4 and ease the traffic burden on the existing roads.
