Jeffersontown is a home rule-class city[3] in Jefferson County, Kentucky, United States.

When the Louisville Metro government was established in 2003, Jeffersontown chose to retain its status as an independent city.

Located in southeastern Jefferson County, along the north central border of Kentucky, Jeffersontown was initially 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 given to veterans for military service following the American Revolutionary War, as the new government was cash poor.

[4][6] A large, 600-acre area from the pioneer days has been preserved since the late 20th century and recognized as the Tyler Settlement Rural Historic District.

Today, Bluegrass Commerce Park has expanded to more than 1,800 acres (7.3 km2) and is home to approximately 850 businesses.

The 38,000 employees who work there make the park and Jeffersontown the third-largest city of employment in the state.

[10][11] In November 2020, the company announced its new global headquarters would be moved to the Three Ballpark Center at The Battery Atlanta.
