Lawtey is a city in Bradford County, Florida, United States. The population was 730 at the 2010 census, up from 656 in 2000.

The city has received national attention and earned the dubious distinction of being one of only two official speed traps designated by the American Automobile Association (the other being Waldo a few miles to the south), due to the city's strict enforcement of the local speed limit on U.S. Route 301 as it cuts through town.
