Sir Andrew Rae Duncan (1884 - 1952) was a British businessman who was brought into government during the Second World War, serving twice as both President of the Board of Trade and Minister of Supply.

Duncan was a Director of the Bank of England and of Imperial Chemical Industries. He was chairman of the British Iron and Steel Federation. He was elected as a National Liberal Member of Parliament for the City of London in a 1940 by-election and was made a member of the Cabinet and a Privy Counsellor. He was re-elected at the 1945 election, stepped down at the 1950 general election and died in 1952.

During his time in ministerial office, there was some concern that someone so closely involved with the iron, steel and chemical industries was in charge of their regulation. However, wartime pressures kept Duncan in post and he was undamaged. He returned to the Iron and Steel Federation after the war, working to resist the Labour government's nationalisation plans with Aubrey Jones, his assistant, later a Conservative minister.

Andrew Duncan (born in 1956) is a British poet, critic, and editor. The author of at least seven books of poetry, including Anxiety Before Entering a Room Selected Poems 1977–99 (Salt Publishing, 2001). His work as a literary and cultural critic is most recently on display in The Failure of Conservatism in Modern British Poetry (Salt Publishing, 2003).

Andrew Duncan studied as a mediaevalist and started his writing career in punk "fanzines". He has been publishing poetry since the late 1970s, serving as the editor of the magazine Angel Exhaust. Duncan worked as a labourer (in England and Germany) after leaving school, and subsequently as a project planner with a telecomms manufacturer (1978–87), and as a programmer for the Stock Exchange (1988–91).
