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, sometimes also referred to as Kentuckiana.
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 is one of Kentucky's nine original counties.
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 head of the Falls of the Ohio. They moved to the mainland the following year, establishing Louisville.
The last major American Indian raid in present-day Jefferson County was the Chenoweth Massacre on July 17, 1789.
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.
According to the U.S. Census Bureau, the county has a total area of 398 square miles (1,030 km2), of which 380 square miles (980 km2) is land and 17 square miles (44 km2) (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 feet (275 m), located in the southern part of the county. The lowest point is 383 feet (117 m) along the Ohio River just north of West Point.

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.
