A district of S Edinburgh, lying a half-mile (1 km) to the south of Colinton, of which it is often considered a part. It was centred on Dreghorn Castle, a large Tudor-baronial mansion, which was built c. 1658 for Sir William Murray who had married, Isobel, the daughter of alocal landowner Sir James Foulis. Dreghorn Barracks were built in the 1930s in the grounds of the castle, which was demolished in 1955. The Bonaly Burn and Howden Burn merge to the NW of the barracks, while the Dreghorn rifle ranges occupied the lower slopes of Allermuir Hill to the south - beyond the A720 Edinburgh Bypass. Dreghorn Link was created at the time of the construction of the bypass to connect Redford Road to Dreghorn Interchange. Dreghorn Services opened in 1990 and represents the only service station on the bypass.
Dreghorn Loan was once an access to Dreghorn Castle. Located here is Laverockdale House, a fine A-listed mansion designed by Sir Robert Lorimer (1864 - 1929) in the Scots-Baronial style for the Edinburgh financier James Ivory and completed in 1912. In 1988, football manager Graeme Souness (b. 1953) built a house in the grounds of Laverockdale House, which was later occupied by disgraced banker Sir Fred Goodwin (b. 1958). The Dreghorn Estate (Dreghorn Drive, Dreghorn Gardens, Dreghorn Grove and Dreghorn Place) was built by the Ministry of Defence c. 1970 to accommodate army families, however Edinburgh Council purchased empty homes here in 2023 to add to their stock of social housing.
