Jefferson County is a county located in the U.S. state of Indiana. As of 2016, the population was 32,683. The county seat is Madison.

History

Jefferson County was formed in 1811. It was named for Thomas Jefferson, principal draftsman of the Northwest Ordinance and President of the United States from 1801 through 1809.

Jefferson County was one of Indiana's first counties and many important early Hoosiers came from Madison, including William Hendricks. Throughout the early history of the state, Madison was one of the leading cities competing with Vincennes and later New Albany to be the largest city in the state. The county fell into economic decline after the American Civil War, as industry began to shift from southern Indiana to the northern part of the state.

On the evening of May 20, 2009 the county courthouse caught fire. The fire began in the steeple of the courthouse, which was under reconstruction for Madison's bicentenary. The roof of the dome had just been painted gold. Fire departments from across southern Indiana and northern Kentucky arrived to put out the fire which burned for several hours, destroyed much of the inside of the building and the county records. The fire forced the evacuation of the nearby county jail, and effectively shut down the downtown area of the city. It was later determined the fire was accidentally started by workers who were welding on the metal roof dome.
