Chilonis is a name historically associated with Spartan princesses, not a securely attested author. The name is linked to a daughter of King Leotychidas II and, more prominently, to the daughter of King Leonidas II and wife of King Cleombrotus II in the third century BCE. None of these figures are recorded as literary authors.

A single work, Chilonis's Letter, is attributed to this name. Its existence and attribution remain unconfirmed in standard scholarly references and catalogs of ancient literature.

Consequently, the literary significance of any such text is indeterminable due to a complete lack of evidence. The historical Chilonis, wife of Cleombrotus II, is remembered for an act of conjugal loyalty, choosing exile with her deposed husband. This renown, however, pertains solely to her role in Spartan political history, not to any authorship.
