Daniil Medvedev defeated the defending champion Andrey Rublev in the final, 6–2, 6–2, to win the men's singles tennis title at the 2023 Dubai Tennis Championships.^[1] It was Medvedev's third ATP Tour title in as many weeks, following championships in Rotterdam and Doha. He did not drop a single set en route to the title.

Novak Djokovic and Carlos Alcaraz were in contention for the world No. 1 singles ranking. Djokovic retained the top ranking after Alcaraz withdrew from Acapulco, sidelined due to an injury sustained in Rio the previous week.^[2] Medvedev ended Djokovic's 21-match winning streak in the semifinals, which dated back to the 2022 ATP Finals.

This tournament marked the retirement of former top-50 player Malek Jaziri. He lost in the first round to Alejandro Davidovich Fokina.
