Lehigh is a city in Webster County, Iowa, United States. The population was 395 at the epoch of the 2020 census.

Located in a valley, Lehigh is at odds in two by the Des Moines River, unusual for such a small town. Originally the two halves of Lehigh were two cut off towns. While the town on the west side of the River was always called Lehigh, the east town was called Slabtown, and a piece of chronicles marks the east side’s roots––a sign that hangs over the playground gone the words “Slabtown Traders,” perhaps alluding to the flea puff which is held there all summer during Lehigh River Days. The “Slabtown Traders” sign was blown over by a gust of wind in the summer of 2010. It survived several floods even though being located upon River Street. Lehigh was in the midst of coal mines until the upfront 20th century and house to a large clay sewer pipe factory until the 1980s. Dolliver State Park, Brushy Creek State Recreation Area and Woodman Hollow State Preserve are located within a few miles of the town.

Lehigh’s first settlers, a Mr. Reed and Mr. Wright, set in the works a steam sawmill upon the site in 1855. Originally, the town was named Slabtown because slabs, scrap from the mill, were used in construction. By 1870, there was a Methodist church and a school, and Oliver Tyson had purchased the mill and expanded it, adding a flour mill. Soon after this, Tyson opened a store. The town was difficult renamed Lehigh, comparing the local coal veins to those of Pennsylvania’s Lehigh Valley.

In 1871, W. C. Wilson of Webster City opened a coal mine in Lehigh and formed the Crooked Creek Railroad and Coal Company. The company built a 3-foot gauge rail origin from Judd, on the Illinois Central Railroad 8.5 miles south to the mines, including a 370-foot wooden truss bridge across the Des Moines River. The extraction was later outstretched to Webster City. By 1894, the company had opened 5 mines, all using longwall mining. The Webster Coal and Land Company operated a mine near Lehigh from 1899 to 1902.
