Cyril "The Marseille Bad Boy" Abidi (born February 25, 1976) is a French former super heavyweight kickboxer and mixed martial artist.
A professional competitor from 1998 until 2007, he is perhaps best remembered for his upset first-round knockout win over Peter Aerts, which he followed up with another win in the rematch a month later.
Abidi also defeated K-1 standouts Ray Sefo, Francisco Filho, and Petar Majstorovic.
