Jefferson County is located in the north central portion of the U.S. Commonwealth of Kentucky. It is the most populous county in the commonwealth (with more than twice the population of second ranked Fayette County).
Since a city-county merger in 2003, the county's territory, population and government have been coextensive with the city of Louisville, which also serves as county seat. The administrative entity created by this merger is the Louisville/Jefferson County Metro Government, abbreviated to Louisville Metro.
Jefferson County is the anchor of the Louisville-Jefferson County, KY-IN Metropolitan Statistical Area, locally referred to as Kentuckiana.

History
Jefferson County was organized in 1780 and one of the first three counties formed out of the original Kentucky County, which was still part of Virginia at the time (the others being Fayette and Lincoln). The county is named for Thomas Jefferson, who was governor of Virginia at the time.
The last major American Indian raid in present-day Jefferson County was the Chenoweth Massacre on July 17, 1789.
Prior to the 2003 merger, the head of local government was the County Judge/Executive, a post that still exists but now has few powers. The office is currently held by Queenie Averette.
Local government is effectively now led by the Mayor of Louisville Metro, Greg Fischer.

Communities
NOTE: Since the formation of Louisville Metro on January 6, 2003, residents of the cities below also became citizens of the newly expanded Metro, but none of the incorporated places dissolved in the process. The functions formerly served by the county government for the towns were assumed by Louisville Metro. However, the former City of Louisville was effectively absorbed into the new city-county government.
