There have been two creations of the title Baron Raby, both in the Peerage of England. The first was in 1640, as a subsidiary title of the Earl of Strafford. The first earl was attainted and his peerages declared forfeit in 1641, but his heir obtained a reversal in 1662. On his death, all his peerages became extinct save the Barony of Raby, which continued until the death of the fifth baron in 1799. Confusingly, the third baron was again created Earl of Strafford in 1711, and the earldom and barony remained merged until their mutual extinction.
