Ayman Abd El Aziz Nour (Arabic: أيمن عبد العزيز نور, IPA: [ˈʔæjmæn ʕæbdelʕæˈziːz ˈnuːɾ]; born 5 December 1964) is an Egyptian politician, a former member of the Egyptian Parliament, founder and chairman of the El Ghad party.

Nour was the first person to compete against President Hosni Mubarak in the 2005 presidential election. Shortly after announcing his candidacy, he was stripped of his parliamentary immunity and arrested on 29 January 2005, a move that was widely criticized by governments around the world as a step backwards for Egyptian democracy. Under international pressure, Nour was released to participate in the election, which was widely considered to be corrupt and rigged. His presidential bid was ultimately unsuccessful. He was arrested again shortly afterward and released nearly five years later.

He was a member of the New Wafd Party until he was removed from the party by Numan Gumaa, who succeeded former party leader Fouad Serageddin.

Nour was named the first secretary of Misr Party and the editor-in-chief of the party's newspaper with the same name in October 2001.

Nour was the first person to ever compete against President Hosni Mubarak in the 2005 presidential election. Shortly after announcing his candidacy for president, Nour was stripped of his parliamentary immunity and arrested on 29 January 2005. He was charged with forging PAs (Powers of Attorney) to secure the formation of the el-Ghad party. The arrest, occurring in an election year, was widely criticized by governments around the world as a step backwards for Egyptian democracy. Few seem to regard the charges as legitimate. Nour remained active despite his imprisonment, using the opportunity to write critical articles and make his case and cause better known.

In February 2005, Condoleezza Rice abruptly postponed a visit to Egypt, reflecting U.S. displeasure at the jailing of Nour, who was reported to have been brutally interrogated. That same month, the government announced that it would open elections to multiple candidates in the following month.

In March 2005, following a strong intervention in Cairo by a group of members of the European Parliament led by Vice-President Edward McMillan-Scott (UK, Conservative), Nour was freed and began a campaign for the Egyptian presidency.

In the election in September 2005, Nour was the first runner-up, with 7% of the vote according to government figures and estimated at 13% by independent observers, although none of them were allowed to monitor the elections. Shortly after placing a distant second, in what are widely believed to have been corrupt elections, he was again imprisoned by Mubarak under allegations of "forgery" which were widely criticized to have been politically motivated and corrupt charges.
