The Alston–Cobb House, now formally known as the Clarke County Historical Museum, is a historic house and local history museum in Grove Hill, Alabama. It was built in 1854 by Dr. Lemuel Lovett Alston as a Greek Revival I-house, a vernacular style also known in the South as Plantation Plain. It is one of only four examples of an I-house to survive intact in Clarke County. The Alston–Cobb House was added to the Alabama Register of Landmarks and Heritage on September 1, 1978, and to the National Register of Historic Places on April 30, 1979.
