Northern Kentucky is an urban area in the U.S. Commonwealth of Kentucky consisting of the southern part of the Cincinnati metropolitan area. The three main counties of the area are Boone, Kenton, and Campbell, all along the Ohio River across from Cincinnati, Ohio. Other counties frequently included in Northern Kentucky include Bracken, Grant, Gallatin and Pendleton. Of Greater Cincinnati's over two million residents, over 450,000 of them live in Northern Kentucky as of 2020, primarily in the northernmost counties. The largest cities in the region are Covington, Florence, and Independence.[1]
Historically, Trimble, Mason, and Lewis Counties have also been included in the broader definition of Northern Kentucky. On July 17, 2019, Brent Cooper, a member of the Northern Kentucky Chamber of Commerce, called for the Northern Kentucky community to consider reuniting three counties (Boone, Kenton, and Campbell) into one county to better reflect the region's common identity and strengthen its political voice and economic marketability.[2]
