Ariphron of Sicyon was a Greek poet from the Classical period, traditionally dated to the 5th–4th centuries BCE. A native of Sicyon in the northern Peloponnese, no biographical details of his life survive.

His sole attested work is the Hymn to Health, a paean to the goddess Hygieia. It survives fragmentarily, primarily through quotation by the 2nd-century CE rhetorician Aelius Aristides. A later prose paraphrase is also attributed to him in some manuscript traditions.

Ariphron’s significance rests on the preservation of this hymn, which was cited in antiquity as an example of a paean. Its inclusion in the Greek Anthology and a reference in Plutarch’s Moralia attest to its later fame. The fragment provides a valuable point of reference for the study of Greek hymnic poetry and the cult of personified abstractions.
