Correctionville is a city in Woodbury County, Iowa, and part of the Sioux City metropolitan area.

Correctionville is supposedly the longest single-word place name in the state of Iowa, and it is often cited as one of America's unusual place names.

Correctionville got its name from geography, not government: it was platted in 1855 on a surveyors' correction line, one of the east-west lines surveyors used to correct for the Earth's curvature when laying out townships.

The survey correction line runs along Correctionville's 5th Street, and because of it no north-south street in town runs straight past 5th Street.

A post office named Correctionville has been in operation since 1862.

Correctionville sits next to the Little Sioux River, and both U.S. Route 20 and Iowa Highway 31 pass through town.

Local students attend River Valley High School in Correctionville, home of the Wolverines; the River Valley district was created in 1996 by merging the Eastwood and Willow school districts.
