In the run up to the 2023 Turkish presidential election, with its first round held on 14 May and a second round on 28 May, various organisations carried out opinion polling to gauge voting intention in Turkey. Results of such polls are displayed in this article. These polls only include Turkish voters nationwide and do not take into account Turkish expatriates voting abroad. The date range for these opinion polls are from the previous general election, held on 24 June 2018, to the present day.
Poll results are listed in the tables below in reverse chronological order, showing the most recent first, and using the date the survey's fieldwork was done, as opposed to the date of publication. If such date is unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's color. In the instance that there is a tie, or that no candidate exceeds 50%, top two candidates' figures are shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty.
