Lexington is an unincorporated community in Lexington Township, Scott County, in the U.S. state of Indiana, located about 10 miles west of the Ohio River and 28 miles north of Louisville, Kentucky. The town itself was founded before Indiana became the 19th state in 1816 and was located in Jefferson County at the time it was platted. It was the original county seat from 1820 to 1874, before local leaders decided on a more central location at nearby Scottsburg, which created animosity between the residents of the two towns for several decades afterwards.

Scott County is a county located in the U.S. state of Indiana. As of 2020, the population was 24,384. The county seat is Scottsburg.
