Deerfield Township was formally established on May 10, 1803, although early settlements of the area date back to the 1790s. The area got its name from the large deer population that was supported by numerous springs that scattered the landscape. Today, Deerfield Township is a vibrant community of 38,000 plus residents in the Cincinnati Metropolitan Area who enjoy a diverse housing stock, excellent schools, a top notch park system, and a bustling retail and entertainment scene. It is the most populous jurisdiction in Warren County comprising over 16 square miles in southwest corner of Warren County and borders both Hamilton and Butler Counties.
