Coughlin House

The Coughlin House is a historic house at 260 West Main Street in Carthage, South Dakota. It is a $2 1/2$-story wood-frame structure with a gable roof. Its main (southern) facade has a centered shed-roof porch supported by spindled columns, with jigsaw-cut balustrade and trim. The house was built in 1898 by James Coughlin, an Irish immigrant, and is a well-preserved local example of Folk Victorian architecture.

The house was listed on the National Register of Historic Places in 2006.
