Ahmed Ayoub Hafnaoui (Arabic: أحمد أيوب حفناوي; born 4 December 2002) is a Tunisian swimmer. He is the African record holder in the long course 400-metre and 1500-metre freestyle, and the short course 800-metre and 1500-metre freestyle events. He competed in the 2020 Summer Olympics, where he won a gold medal in the men's 400-metre freestyle. He ranked No. 16 in the world and was the slowest qualifier for the final race but won Olympic gold with a time of 3:43.36. Hafnaoui was the only Tunisian to win Olympic gold at Tokyo 2020.

He finished 8th in the final of the 400 m freestyle at the 2018 Summer Youth Olympics in Buenos Aires.

Hafnaoui competed as a 16-year-old at the 2018 World Championships (SC) in the 400 meters, and the 1500 meters, but failed to make the final in either events. In 2021, Fina had him ranked as No. 3 in the men's 400 meter freestyle. At the age of 20, Hafnaoui competed at the 2023 World Championships in Fukuoka, and took gold in the 800 m freestyle, as well as also winning gold for the 1500 m freestyle with the second-fastest 1500 free time in history of 14:31.54.

Hafnaoui is currently serving a 21-month competition ban due to expire in January 2026 for an anti-doping rule violation after missing three tests in a 12-month period.
