Kenneth City is a town in southern Pinellas County, Florida, between St. Petersburg and Pinellas Park, United States. Kenneth City was founded in 1957 by Sidney Colen, a local developer, who named the city after his son Kenneth Colen. The population was 4,980 at the 2010 census. The town, small in area and set amidst dense residential developments mostly with otherwise indistinguishable town boundaries, has earned a reputation as a speed trap town for the vigorous enforcement of its lower speed limits.
