# 2023 Dubai Tennis Championships – Men's singles

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. 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. 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.
