Hafnaoui's father Mohamed was a Tunisian national-team basketball player, but the son chose swimming, which he began at the age of six; at twelve he joined the national swim programme, in a country that then had just three 50-metre pools. ¹ He finished eighth in the 400 m freestyle final at the 2018 Youth Olympics in Buenos Aires and won medals at the 2018 African Championships in Algiers. ¹

At Tokyo 2020 Hafnaoui was ranked sixteenth in the world and was the slowest qualifier for the 400 m freestyle final; swimming from lane 8, he won gold in 3:43.36, becoming only the third swimmer in history to win an Olympic title from the outside lane, and Tunisia's only gold medallist of those Games. ¹ At the 2021 short-course World Championships in Abu Dhabi he took silver in the 1500 m freestyle in an African record of 14:10.94. ¹ At Fukuoka in 2023 he won gold in the 800 m and 1500 m freestyle — the latter in 14:31.54, the second-fastest time in history — and silver in the 400 m freestyle. ¹ He holds the African records in the long-course 400 m and 1500 m freestyle and moved to Indiana University in 2023. ¹ Tunisia awarded him the First Class of the National Order of Merit in August 2021. ¹

In April 2025 Hafnaoui was suspended for twenty-one months for an anti-doping rule violation, having missed three tests within twelve months. The ban was backdated to 11 April 2024 and runs to 10 January 2026; it made him ineligible for the Paris 2024 Olympics, and his results from April 2024 onwards were disqualified. ¹
