Iliass Aouani (born 29 September 1995) is an Italian middle and long-distance runner who set a new Italian national marathon record of 2:04:26 at the 2026 Tokyo Marathon.
Born in Fquih Ben Salah, Morocco, Aouani moved to Italy when he was 2, and grew up in the Province of Milan between Sesto San Giovanni and Ponte Lambro. He started running when he was 16, and in 2014, under the guidance of the former coach of Gennaro Di Napoli Claudio Valisa, he got the national junior 5000 metres title. He studied at Lamar University and later at Syracuse University, earning a bachelor's degree in civil engineering and a master's degree in structural engineering.
In 2021, Aouani moved to Ferrara to focus on his athletic career, training under Massimo Magnani; the same year, he won 4 national titles. In 2024, he achieved the second-fastest Italian time ever at the Valencia Marathon. In 2025, he won the gold in the men's marathon at the European Running Championships, and the bronze in the same discipline at the World Athletics Championships, 22 years after the latest Italian medallist Stefano Baldini.
Aouani won five national championships at individual senior level.
