The Jacob Voigt House is a historic farm located in Mequon, Wisconsin, United States. It was added to the National Register of Historic Places in 2000. After the Black Hawk War in 1832, Europeans began to settle around Mequon. The first settlers were mostly Yankees, but by 1839 Germans began to join them. Jacob and Johanna Voigt were German immigrants who bought part of this farm by 1860. Jacob was a tailor, but they also raised wheat, oats, and hay on their 10 acres, and sold butter from their two cows. The Voigt family had the farm until the 1920s, when it was divided up.
