Clive Adrian Stafford Smith OBE (born 9 July 1959) is a British attorney who specialises in the areas of civil rights and working against the death penalty in the United States of America.

Born in Cambridge and educated at Old Buckenham Hall School and Radley College, Clive Stafford Smith studied journalism as a Morehead Scholar at the University of North Carolina at Chapel Hill.

After returning to Britain, Stafford Smith worked as the founder of Reprieve, a British non-profit NGO that is opposed to the death penalty.

[4] During his career in the US, by 2002 Stafford Smith had lost appeals in six death penalty cases, but had won nearly 300, earning reprieves from execution for those convicts and exonerating a number of them.

[2] From 2002 Stafford Smith volunteered his services to detainees held as enemy combatants at the United States detainment camp at Guantanamo Bay, established under President George W. Bush as part of the Global War on Terror.

In an interview broadcast by BBC television evening news on 9 September 2005, Stafford Smith said that the second hunger strike was to protest against the imprisonment of juveniles under the age of 18 in Guantanamo Bay.

[10] Stafford Smith contributed to The Guardian with an opinion piece on the significance of the U.S. Supreme Court's 29 June 2006 ruling in Hamdan v. Rumsfeld, which found the Combatant Status Review Tribunals and military commissions to be unconstitutional.

[12] Interviewed by Jon Snow of Channel 4 News on 26 March 2009, Stafford Smith said about the treatment of detainees, "I would go one step further: the torture decisions were being made in the White House, by the National Security Council, Dick Cheney and Condoleezza Rice."

[13] In July 2010, Stafford Smith accused former Foreign Secretary David Miliband of fighting to prevent the release of vital documents during the Binyam Mohamed case.

[14] In 2022, Stafford Smith was featured in the documentary film We Are Not Ghouls, about his work with JAG attorney Yvonne Bradley to free Guantanamo detainee Binyam Mohamed.
