Heighe House is a historic home complex and national historic district at Bel Air, Harford County, Maryland, United States. The complex consists of a Colonial Revival, 2+1⁄2-story stone main house built on and incorporating the stone foundations of the Moores Mill, built in 1745; a 1+1⁄2-story frame chauffeur's cottage; garage; and a 1+1⁄2-story stone and frame guest house. They are all located on a steeply sloping 17-acre (69,000 m) site along Bynum Run. The property was developed in 1928 as a country estate for Anne McElderry Heighe (d. 1953), a woman widely regarded as the "first lady of Maryland racing."

It was added to the National Register of Historic Places in 1990.
