Abdulrahman al-Nuaimi (1943/1944 – September 1, 2011) was a Bahraini politician and opposition leader. Al-Nuaimi, who spent more than thirty years in self-imposed exile from Bahrain, founded some of the country's most important political opposition groups.
He was born in 1944 on Muharraq island to the Sunni Al Nuaim family that has close ties to the traditional ruling circles. In the 1960s he became increasingly politically active and joined the Arab Nationalist Movement. In 1966 he graduated from the American University of Beirut with a degree in mechanical engineering.
He founded the Popular Front for the Liberation of Bahrain (PFLB), a resistance group, during the 1970s. The groups was inspired by the Arab Nationalist Movement which was sweeping though the Arab World at the time.
After a crackdown on the workers' movements at the power station where he was working in 1968, he left Bahrain to live in exile, spending 33 years in Damascus.
In 2001, al-Nuaimi returned to Bahrain from aboard and re-entered politics. He founded the National Democratic Action Society (NDA), Bahrain's largest leftist political party, with members of the former PFLB.
The NDA is also known as the Wa'ad party. Al-Nuaimi ran for a seat in the Council of Representatives of Bahrain during the 2006 parliamentary election, but lost to a pro-candidate candidate by a small margin.
