Sir Gilbert James Morley Longden (16 April 1902 – 16 October 1997) was a British Conservative politician.
He fought Morpeth unsuccessfully in 1945 and then served as Member of Parliament for South West Hertfordshire from 1950 until his retirement in February 1974.
He was one of the last surviving members of the One Nation Group of Conservative Members of Parliament, who included Harold Macmillan, Rab Butler, Enoch Powell, Edward Heath, Iain Macleod and Angus Maude.
Famously, when Macmillan sacked a third of his Cabinet on what was known as "The Night of the Long Knives", Longden the next day said "May I congratulate the Prime Minister on having kept his head when all around were losing theirs" - the opposition collapsed in laughter.
