Sikyonios or Sikyonioi (), translated as The Sicyonian(s) or The Man from Sicyon, is an Ancient Greek comedy by Menander. About half of the play has survived in fragments of papyrus used to stuff several mummies in the cemetery of Medinet-el-Ghoran in the Faiyum, where they were discovered in 1901 by Pierre Jouguet. The first acts are almost completely lost, but the rest, although the manuscript is often corrupt, lacunose and hard to read, allows a fair reconstruction of the plot.
