thumb|The Grifone figure (right of picture) has been identified with Zanclus.
Zanclus (; , ) is the legendary first king of the Sicilian city of Messina. He is mentioned in an etiological passage by Diodorus of Sicily, and has become a symbol of Messina. In modern Italian, the form is given as Zanclo.
Zanclus has been identified with the male "Grifone" figure of Messina's traditional Mata e Grifone procession. The earliest records, by Francesco Maurolico, record only one the male figure, and associate it with Zanclus. When Zanclus is identified with the male figure in modern times, his female partner is identified as the Titaness Rhea.
Stephanus of Byzantium also wrote about Zanclus, stating that Zancle could have been named either after him or the well Ζάγκλη.
