Baron Rugby, of Rugby in the County of Warwick, is a title in the Peerage of the United Kingdom. It was created in 1947 for the civil servant Sir John Maffey. He was Governor-General of the Sudan between 1926 and 1933 and Permanent Under-Secretary of State for the Colonies between 1933 and 1937. The title is now held by his grandson, the third Baron, who succeeded his father in 1990.
The Hon. Penelope Aitken, mother of the former Conservative politician Jonathan Aitken and of the actress Maria Aitken, was the daughter of the first Baron Rugby.
