Sir Patrick William Donner (4 December 1904 – 19 August 1988) was a British Member of Parliament (MP) and a member of the influential Finland-Swedish Donner family.
His family moved from Helsinki, Finland, to London in 1919. His mother was Scottish Violet McHutchen and his father was Ossian Donner, who headed Finland's first diplomatic mission in London 1919 to 1925. The family later settled in England for good, and his father became a British citizen.
Donner studied English literature at Exeter College, Oxford and later entered business. He was elected at the 1931 election as Conservative MP for Islington West. The seat being marginal, Donner was selected for the safe Conservative seat of Basingstoke for the 1935 election against the wishes of Conservative Central Office, who preferred Sir Francis Oswald Lindley.The papers of Sir Henry Maxence Cavendish Drummond Wolff appear to indicate that Sir Oswald Mosley interviewed Donner to decide upon his suitability to serve as MP for the Basingstoke constituency, which had previously been held by two fascists, Drummond Wolff and Viscount Lymington.
