Port St. Lucie is a city in St. Lucie County, Florida, on the state's Treasure Coast. It is the most populous municipality in the county and the sixth-most populous city in Florida, with a population of 204,851 at the 2020 census. The city lies about 125 miles southeast of Orlando and 113 miles north of Miami, positioning it between the attractions of central Florida and the metropolitan areas of South Florida. Port St. Lucie developed largely as a planned community beginning in the mid-twentieth century, and that planned character remains central to its identity today. The city is known for its master-planned neighborhoods, golf communities, and family-oriented amenities. PGA Village anchors the city's golf reputation with 54 holes of championship golf, while Clover Park serves as the spring training home of the New York Mets and hosts minor league baseball through the season. The St. Lucie River runs through the region, offering boating, kayaking, and fishing, and the city's parks, preserves, and botanical gardens provide outdoor recreation. The master-planned community of Tradition, with its town center and shops, anchors the western side of the city, while the eastern sections sit closer to the river and the older part of town. The city's large land area and planned layout distinguish it from older Florida cities, with residential neighborhoods connected by broad arterial roads and expressways. Employment and services are distributed across its commercial corridors, while the county seat of Fort Pierce lies to the north and the Treasure Coast beaches to the east. The St. Lucie River and the Indian River Lagoon frame the area's coastal geography. Public education is provided by the St. Lucie County School District. With its combination of planned communities, golf, spring training baseball, and river access, Port St. Lucie functions as a large residential city that draws families and retirees seeking an amenity-rich lifestyle on the Treasure Coast.
