Winston Joseph Field CMG MBE (6 June 1904 – 17 March 1969) was a British politician who served as the seventh Prime Minister of Southern Rhodesia.

[2] Field then transferred to the British Forces, joining the Worcestershire Regiment as a Second Lieutenant from 1941, served in the D-Day Normandy landings in 1944, and ended the war with the rank of Major in the 6th Durham Light Infantry.

Field lent an air of respectability to the Rhodesian Front government, though his Cabinet was derided by one newspaper as "by no means an inspiring list".

On the contrary, they see him as a man of cold reserve, not softened by his past defeats, not at all intimidated by the terrible power over other men’s lives now put into his hands by the white voters of Southern Rhodesia.

Field's Cabinet included John Gaunt, a former Federal MP for Lusaka and a former District Commissioner in Northern Rhodesia.

Field was replaced as leader of the Rhodesian Front and as Prime Minister of Rhodesia by Ian Smith on 14 April 1964, despite the Governor Sir Humphrey Gibbs urging him to fight against the rebels in his party.
