The Seth Peterson Cottage is a one-story cottage in Mirror Lake State Park near Reedsburg in the U.S. state of Wisconsin. Designed by Frank Lloyd Wright with Thomas Casey as the supervising architect, the house was built for computer operator Seth Peterson of Black Earth, Wisconsin, and was one of Wright's last designs. The exterior of the building has ashlar foundations and large glass windows. The cottage has a bedroom and a living–dining room, which encircles a utility core composed of a kitchen and bathroom. The roof above the bedroom is flat, while the rest of the cottage has a sloped roof. The house is on the National Register of Historic Places.
