The Louisville-Jefferson County, KY-IN Metropolitan Statistical Area, commonly called the Louisville metropolitan area or Kentuckiana, is the 42nd largest Metropolitan Statistical Area (MSA) in the United States. The primary city is Louisville, Kentucky.

It was originally formed by the United States Census Bureau in 1950 and consisted of the Kentucky county of Jefferson and the Indiana counties of Clark and Floyd. As surrounding counties saw an increase in their population densities and the number of their residents employed within Jefferson County, they met Census criteria to be added to the MSA. Jefferson County, Kentucky (contiguous with Louisville Metro), plus twelve outlying counties — eight in Kentucky and four in Southern Indiana are now a part of this MSA.

People living in any of the MSA are said to be living in the Louisville/Jefferson County Area. Because it includes counties in Indiana, the MSA (or a large portion thereof) is regularly referred to as Kentuckiana. It is now the primary MSA of the Louisville–Elizabethtown–Madison, KY–IN Combined Statistical Area (or Louisville CSA, which adds Hardin County, Kentucky, LaRue County, Kentucky, and Jefferson County, Indiana). The combined statistical area created by the United States Bureau of the Census in 2000, comprises the Louisville – Jefferson County, KY–IN Metropolitan Statistical Area (MSA), the Elizabethtown, KY Metropolitan Statistical Area, and the Madison, Indiana Micropolitan Statistical Area (also abbreviated as MSA).
