Perry County is a county located in the U.S. state of Illinois. According to the 2010 census, it had a population of 22,350.  Its county seat is Pinckneyville.  It is located in the southern portion of Illinois known locally as " Little Egypt".
Perry County was formed in 1827 out of Jackson and Randolph counties. It was named in honor of Oliver Hazard Perry who defeated the British fleet at the decisive Battle of Lake Erie in the War of 1812.
In its early history, Perry County was mainly an inland pioneer outpost. Early settlers, including some Revolutionary War veterans bearing land grants, moved here from the Eastern United States. These were primarily Protestant settlers. Growth boomed in the 1850s for two reasons: construction of the Illinois Central Railroad through the eastern portion of the county, and the discovery of large coal reserves. Immigrants from Ireland, Poland, Germany, Italy and elsewhere steadily increased the County's population from 1850 through the 1920s. African Americans also were established in the County during northward migration following the Civil War.
Mining continued to be the dominant employment sector through the 1990s.
Perry County is located in Southern Illinois. Pinckneyville, at the center of the county, is approximately 70 miles (110 km) southeast of St. Louis, Missouri and 300 miles (480 km) southwest of Chicago. The Mississippi River lies about 10 miles (16 km) west and southwest of the County at its closest point.
The County's topography is mainly flat with some rolling hills. The part of the County's eastern border, the part shared with Franklin County, is formed by the Little Muddy River. Beaucoup Creek runs north to south through the County and lies just east of Pinckneyville.
The county's topography also features many "strip cut" lakes, lakes left behind following above-ground coal mining. Lakes at two of the county's chief recreation areas, the Du Quoin State Fairgrounds and Pyramid State Recreation Area, were formed this way.
