Pinellas Park is a city located in central Pinellas County, Florida, United States. The population was 49,079 at the 2010 census. Originally home to northern transplants and vacationers, the hundred year old city has grown into the fourth largest city in Pinellas County, the most densely-populated county in Florida. The city and surrounding areas are almost completely urbanized. Pinellas Park contains a substantial portion of the "Gateway" area of the county, targeted for future infrastructure, residential, and commercial development as it sits roughly in the middle of Tampa Bay's 2+ million people. Though technically land-locked, its borders lie only a few miles from Tampa Bay to the east, and Boca Ciega Bay and the Gulf of Mexico to the west. The city is known for its popular equestrian facilities and events, and many residents also participate in fishing and water activities in nearby venues. On Park Boulevard, the city's oldest street and primary thoroughfare, one can find anything from produce stalls and flea markets to high-end luxury vehicles.
