David Morris (28 January 1930 – 24 January 2007) was a Welsh politician, Member of the European Parliament (MEP), chairman of Campaign for Nuclear Disarmament (CND) Cymru and peace activist.
Morris was born in Kidderminster, but adopted by a Welsh family. He joined the Labour Party at the age of fifteen, and as a young man he worked in a steel foundry in Llanelli, South Wales. During National Service in the late 1940s he was exempted from military service as a conscientious objector, conditional upon working down coal mines.
He gained a scholarship to Ruskin College, Oxford, and became a Presbyterian minister in 1958.
Morris became an anti-nuclear campaigner in 1957, opposing Operation Grapple X, in which Britain tested nuclear weapons including its first hydrogen bombs over the Pacific Ocean atoll of Christmas Island (now Kiritimati).
Morris served as a Labour Party Councillor in South Wales, and unsuccessfully contested Brecon and Radnorshire at the 1983 general election before being elected in 1984 as the Member of the European Parliament (MEP) for Mid and West Wales. After boundary changes he served until 1999, latterly representing South Wales West, an area corresponding to Swansea, Neath Port Talbot and Bridgend.
