The Simon Cameron House, also known as John Harris Mansion and the Harris–Cameron Mansion, is a historic house museum at 219 South Front Street in Harrisburg, Pennsylvania. Built in 1766 and frequently extended and altered, it is one of Harrisburg's oldest buildings, and is nationally notable as the summer residence of Simon Cameron (1799–1889), an influential Republican Party politician during and after the American Civil War. The house and family items were donated to the Historical Society of Dauphin County in 1941, which now operates it as a museum. The mansion was declared a National Historic Landmark in 1975, and is located in the Harrisburg Historic District.
