Posey County is the southernmost, southwesternmost, and westernmost county in the U.S. state of Indiana. Its southern border is formed by the Ohio River, and its western border by the Wabash River, a tributary to the Ohio. As of 2010, the population was 25,910. The county seat is Mount Vernon.
Posey County is part of the Evansville, IN–KY Metropolitan Statistical Area. The Ports of Indiana-Mt. Vernon, on the Ohio River, is the seventh largest inland port complex in the nation. Mechanization of dock technology has altered the number of workers at the port, but Posey County is still the seventh-largest internal port in the United States, based on the tons of materials handled. Grain from the Midwest is among the products shipped.
Posey County was formed on November 11, 1814 from Gibson and Warrick counties. It was named for Revolutionary War Gen. Thomas Posey, who was then serving as Governor of the Indiana Territory. Mount Vernon became the county seat in 1825.
According to the 2010 census, the county has a total area of 419.32 square miles (1,086.0 km2), of which 409.57 square miles (1,060.8 km2) (or 97.67%) is land and 9.75 square miles (25.3 km2) (or 2.33%) is water. The lowest point in the state of Indiana is located on the Ohio River in Posey County, where the waters of the Wabash River join it and flow out of Indiana and into Illinois and Kentucky.
