Halsbury is a historic manor in the parish of Parkham in North Devon, England. It is situated 2 miles north-east of the village of Parkham and 4 miles south-west of the town of Bideford. Halsbury was long a seat of the ancient Giffard family, a distant descendant of which was the celebrated lawyer Hardinge Stanley Giffard, 1st Earl of Halsbury (1823–1921), who adopted the name Halsbury for his earldom and was the author of the essential legal reference books Halsbury's Statutes. Halsbury Barton, now a farmhouse, retains 16th- and 17th-century elements of the former manor house of the Giffard family. It was described in a record of 1560 as a "new dwelling house".

Hardinge Stanley Giffard, 1st Earl of Halsbury, PC was a British barrister and Conservative politician. He served three times as Lord High Chancellor of Great Britain, for a total of seventeen years, a record not equaled by anyone except Lords Hardwicke and Eldon.
