Presidential elections were held in Tunisia on 15 September 2019, the second direct vote for the presidency since the 2011 revolution. The elections had originally been planned for 17 and 24 November, but were brought forward after the death of incumbent president Beji Caid Essebsi on 25 July to ensure that a new president would take office within 90 days, as required by the constitution.
As no candidate received a majority of the vote in the first round, a runoff was held on 13 October between the top two candidates, Kaïs Saïed and Nabil Karoui.
