Geoffrey Audus Nicholson Hirst TD (14 December 1904 – 18 June 1984) was a British industrialist and politician who was a maverick Conservative Member of Parliament.
Hirst, from a Yorkshire military family, was educated at Charterhouse School and St John's College, Cambridge.
During the Alec Douglas-Home government, Hirst objected to Edward Heath's bill to abolish resale price controls, and jibed that the reason the negotiations for the United Kingdom to join the European Economic Community had failed was that there was no room in Europe for two de Gaulles.
Following the 1966 general election, he launched a single-handed campaign against the Wilson government's Prices and Incomes Bill.
He sat through the rest of the Parliament as an Independent Conservative, but did not attempt to retain his seat at the 1970 general election.
