Four other defendants, including his former adviser Imed Daimi and former head of the national bar association Abderrazak Kilani, were also handed the same sentence late Friday.
A staunch critic of President Kais Saied who has been living in France, Marzouki had already been sentenced in absentia to 12 years in prison in two separate cases, one involving "provoking disorder".
The latest ruling came after a press conference held in Paris, during which he, along with Daimi and Kilani, sharply criticised state institutions and members of the Tunisian judiciary, reports said.
Marzouki, who served as Tunisia's third president from 2011 to 2014, said in a statement the ruling was "surreal".
He said it came as part of a "series of verdicts that have targeted some of Tunisia's finest men and continue to provoke the world's mockery".
Tunisia was widely seen as a leading example of democratic change in the Arab world following the 2011 ousting of longtime ruler Zine El Abidine Ben Ali.
But since a sweeping power grab by Saied in July 2021 when he dissolved parliament and began ruling by decree, rights groups have warned of a sharp decline in Tunisian civil liberties.
In April, a mass trial saw around 40 public figures, mainly critics of the authorities, sentenced to long terms on charges including plotting against the state.
Other media figures and lawyers also critical of Saied have been prosecuted and detained under a law he enacted in 2022 to prohibit "spreading false news".
