Daniil Medvedev won the men's singles tennis title at the 2026 Dubai Tennis Championships after Tallon Griekspoor withdrew from the final due to a left-hamstring injury. He did not drop a set en route to his 23rd ATP Tour title and second title in Dubai (after 2023). This was the first time Medvedev won a second title at the same tournament. This was the seventh time that an ATP Tour singles final ended in a walkover, and the first since 2017.
Stefanos Tsitsipas was the defending champion, but lost in the first round to Ugo Humbert.
