Lehigh is a city in Webster County, Iowa, United States. The population was 416 at the 2010 census.
Located in a valley, Lehigh is divided in two by the Des Moines River, unusual for such a small town. Originally the two halves of Lehigh were two separate 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 history marks the east side's roots––a sign that hangs over the playground with the words "Slabtown Traders," perhaps alluding to the flea market that occurs there every 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 while being located on River St. Lehigh was surrounded by coal mines until the early 20th century and home 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.
