Diophilus or Diophila is a figure for whom no biographical information exists. The name is absent from major encyclopedias and digital libraries of classical texts, including the Stanford Encyclopedia of Philosophy, the Oxford Research Encyclopedia of Classics, and the Perseus Digital Library. The figure is identified in metadata as a 3rd-century BCE Hellenistic poet, but no corroborating details regarding geography or associations are available.

A single, untitled poetic work is attributed to this author, transmitted only in fragmentary form in the Koine dialect. No description or content from the work is recorded in the consulted sources.

The historical importance and influence of Diophilus or Diophila cannot be determined. The absence from standard reference works suggests the figure is extremely obscure, the subject of highly specialized scholarship, or that the name may be an alternate reference to a more known individual.
