(AI translated) Ahmed Néjib Chebbi (Arabic: أحمد نجيب الشابي), also known simply as Néjib Chebbi (or Ahmed Néjib Chabbi), was born on 30 July 1944 in Tunis. He is a Tunisian lawyer and politician.

A prominent left-wing activist and one of the leading figures of the opposition to the regime of Zine El Abidine Ben Ali, Chebbi co-founded the Progressive Socialist Rally (RSP) (Arabic: التجمع الاشتراكي التقدمي) in 1983. The party was one of several political parties established following the 1981 legislative elections and was officially legalized after 7 November 1987.

Chebbi led the party, which was renamed the Progressive Democratic Party (PDP) in 2001. In 2006, after 23 years as its leader, he stepped down as Secretary-General, handing over the position to Maya Jribi, the first woman to lead a political party in Tunisia.

In 2009, Chebbi sought to run in the presidential election despite not meeting the eligibility criteria imposed by the electoral framework. One month before the official submission of candidacies, he withdrew from the race, denouncing what he described as a predetermined and unfair electoral process.

Following the fall of Ben Ali on 14 January 2011, Chebbi served for several weeks as Minister of Regional and Local Development in the transitional government before being elected as a member of the National Constituent Assembly.

On 26 April 2022, amid Tunisia's ongoing political crisis, Chebbi announced the creation of the National Salvation Front, a coalition bringing together several political parties and movements, including Ennahdha, Qalb Tounes (Heart of Tunisia), the Coalition of Dignity, Hizb el-Harak, Al Amal, and the Citizens Against the Coup movement, with the stated aim of opposing President Kaïs Saïed's policies.

On 4 December 2025, Chebbi was arrested at his home in Tunis following the appeal judgment pronounced on 27 November 2025 in the widely known "conspiracy against the internal and external security of the State" case involving several political opponents. On appeal, he was sentenced to 12 years' imprisonment, after having initially received an 18-year prison sentence at first instance.
