Darby Dan Farm is a produce, livestock, and thoroughbred horse breeding and training farm founded in 1935 near the Darby Creek in Galloway, Ohio by businessman John W. Galbreath. Named for the creek and for Galbreath's son, Daniel M. Galbreath (1928-1995), it was expanded from an original 85-acre (340,000 m2) farm into a 4,000 acre (16 km²) estate. Established in 1954 on the original area, Darby House today serves as a banquet and retreat facility.
