Hermesianax of Cyprus (Ἑρμησιάναξ ὁ Κύπριος) was a Hellenistic historian who lived in the 4th–3rd century BCE. He is known solely from a citation by Athenaeus of Naucratis, who identifies him as a Cypriot and references his historical work. No other biographical details survive [1].

His only attested work is a lost historical text, which Athenaeus quotes for a reference to the poet Philoxenus of Cythera. Neither fragments nor a specific title are preserved [1].

Hermesianax’s significance rests on his status as a fragmentary Hellenistic historian from Cyprus, illustrating the spread of Greek historical writing during the period. He exists within the tradition of lost authors whose works were utilized by later compilers like Athenaeus [1].
