Gaetano Di Giovanni claimed his face was scratched and bruised after Miss Campbell, 38, allegedly slapped him and hit him with her handbag.
Miss Campbell's representative denied the attack took place and said in a statement: "Media reports circulating that Naomi Campbell attacked a photographer in Lipari, Sicily are completely untrue.
"The photographer was seen following Naomi Campbell on a small boat, taking photographs, the day after the alleged incident."
Mr Di Giovanni told the Italian newspaper: "First she hit with her bag, screaming at me and then she tried to slap me. I managed to avoid her – but her nails still got my eye. For a few seconds I could not see a thing. I could hear that her bodyguards and her boyfriend were trying to drag her away."
Police on Lipari said no complaint had been made to them.
