Indiana County is a county located in the West central part of the U.S. state of Pennsylvania. As of the 2010 census, the population was 88,880. Its county seat is Indiana. Indiana County comprises the Indiana, PA Micropolitan Statistical Area, which is also included in the Pittsburgh-New Castle-Weirton, PA-WV-OH Combined Statistical Area.

Prior to the American Revolutionary War, some settlers proposed this as part of a larger, separate colony to be known as Vandalia, but opposing interests and the war intervened. Afterward, claims to the territory by both the states of Virginia and Pennsylvania had to be reconciled. After this land was assigned to Pennsylvania by the federal government according to the placement of the Mason–Dixon line, Indiana County was created on March 30, 1803, from parts of Westmoreland and Clearfield counties and was formally organized in 1806.


According to the U.S. Census Bureau, the county has a total area of 834 square miles (2,160 km2), of which 827 square miles (2,140 km2) is land and 7.3 square miles (19 km2) (0.9%) is water.
