The James P. Hidley Cottage is a small Carpenter Gothic house in western Butler County, Ohio, United States. Erected in 1860, the house is important as one of the area's few houses of its style, and it has been named a historic site. In 1980, the Hidley Cottage was listed on the National Register of Historic Places, a distinction now held by more than eighty locations countywide. It qualified for designation based on its historically significant architecture, as very few authentic Carpenter Gothic houses built in Butler County have survived to the present day.
