The Loraine Baronetcy, of Kirk Harle in the County of Northumberland, was a title in the Baronetage of England. It was created on 26 September 1664 for Thomas Loraine, High Sheriff of Northumberland. The second Baronet was Member of Parliament for Northumberland. The third Baronet was High Sheriff of Northumberland in 1742, the fourth Baronet in 1774 and the fifth Baronet in 1814. The eleventh Baronet was a Rear-Admiral in the Royal Navy. The twelfth Baronet was a distinguished diplomat. The title became extinct on his death in 1961.
The Loraines trace their ancestry back to Robert de Loraine a Norman knight who arrived in England with William the Conqueror. The Northumbrian estate at Kirkharle Hall was acquired when William Loraine married the Strother heiress of Kirk Harle early in the 15th century. Capability Brown was born at Kirk Harle and was employed as a youth on the estate by the second Baronet.
