It is a major suburb of Louisville: when the Louisville Metro government was established in 2003, Jeffersontown remained an independent city. It is the metro area's largest municipality outside Louisville. It is also as of 2018 the fourteenth largest city in the state.
This was an area of game, especially bison, when occupied by Native Americans for centuries before European encounter. the bison created paths through the forests and meadows later used by Native Americans and Europeans alike.
Located in southeastern Jefferson County, along the north central border of Kentucky, Jeffersontown began to be developed in the late 1700s as a stopover and trading station for early European-American pioneers on their way to the Falls of the Ohio at Louisville. Farmers began to cultivate the rich land, which was surveyed by Thomas Bullitt in 1773 and John Floyd the next year. The Hites, Tylers, and Oldhams all settled the area under land grants for military service following the American Revolutionary War. 
In 1794, Abraham Bruner purchased 122 acres (49 ha) of land. In May 1797,  he successfully petitioned the Jefferson County Fiscal Court to incorporate a 40-acre (16 ha) section of his land as the city of Jefferson – named either after the county or after Thomas Jefferson, then the vice president of the United States. The city was long known as Bruner's Town or Brunerstown by its inhabitants, but the usage Jefferson Town eventually led to its present name.  
A large, 600-acre area from the pioneer days has now been preserved and recognized as the Tyler Settlement Rural Historic District. It is used largely for agricultural purposes. This district is east of Jeffersontown and has several of the Tylers' original log cabins and barns. A large portion of the Tyler settlement is known as the Blackacre Nature Preserve. This 170-acre tract is used by Jefferson County public schools as part of their environmental education.
