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 injury sustained in Rio the previous week.[2] Medvedev ended Djokovic's 21-match winning streak in the semifinals which dated back to 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.
