The Guildford Four and Maguire Seven were two groups of people, mostly Irish, who were wrongly convicted in English courts in 1975 and 1976 for the Guildford pub bombings of 5 October 1974, and the Woolwich pub bombing of 7 November 1974. All the convictions were eventually quashed after long campaigns for justice, and the cases, along with those of the Birmingham Six, diminished public confidence in the integrity of the English criminal justice system.

The Birmingham Six were six Irishmen who were each sentenced to life imprisonment in 1975 following their false convictions for the 1974 Birmingham pub bombings. Their convictions were declared unsafe and unsatisfactory and quashed by the Court of Appeal on 14 March 1991. The six men were later awarded financial compensation ranging from £840,000 to £1.2 million.
