The James Whallon House is a historic former farmhouse in the village of Greenhills near Cincinnati, Ohio, United States. It was at least the third Ohio home of James Whallon and his family, who settled in the region in 1800, purchased the land around the present house in 1806, and built a log cabin on the property before constructing the present house in 1816. In 1973, the James Whallon House was listed on the National Register of Historic Places. It qualified for inclusion both because of its well-preserved historic Federal architecture and because of its connection to James Whallon.
