Jefferson County is a county located in the north central portion of the U.S. state of Kentucky. As of the 2020 census, the population was 782,969. 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—originally Jefferson County, Virginia—was established by the Virginia General Assembly in June 1780, when it abolished and partitioned Kentucky County into three counties: Fayette, Jefferson and Lincoln. Named for Thomas Jefferson, who was governor of Virginia at the time, it was one of Kentucky's nine original counties on June 1, 1792.

In 1778, during the American Revolutionary War, George Rogers Clark's militia and 60 civilian settlers established the first American settlement in the county on Corn Island in the Ohio River, at the head of the Falls of the Ohio. They moved to the mainland the following year, establishing Louisville.
Richard Mentor Johnson, the 9th Vice President of the United States, was born in Jefferson County in 1780, while the family was living in a settlement along the Beargrass Creek.
The last major American Indian raid in present-day Jefferson County was the Chenoweth Massacre on July 17, 1789.
Geography
According to the United States Census Bureau, the county has a total area of 398 sqmi, of which 380 sqmi is land and 17 sqmi (4.3%) is water. The Ohio River forms its northern boundary with the state of Indiana.
The highest point is South Park Hill, elevation 902 ft, located in the southern part of the county. The lowest point is 383 ft along the Ohio River just north of West Point.

Government and politics
Whenever possible, the metro government generally avoids any self-reference including the name "Jefferson County" and has even renamed the Jefferson County Courthouse as Metro Hall.
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, Craig Greenberg.
Like most urban counties nationwide, Jefferson County is currently a Democratic stronghold. Jefferson County has voted for the Democratic candidate in every presidential election since 1992. In the 2019 gubernatorial election, it voted for Democrat Andy Beshear by a higher percentage than any other county in Kentucky, giving him 67% of the vote. The county voted "No" on 2022 Kentucky Amendment 2, an anti-abortion ballot measure, by 71% to 29%, outpacing its support of Joe Biden during the 2020 presidential election.
