Qus (Arabic:قوص, derived from Ancient Egyptian Gesa or Gesy‎) is a city in the modern Qena Governorate, Egypt, located on the east bank of the Nile. Its modern name is one of many borrowings in Egyptian Arabic from Coptic, the last living phase of Ancient Egyptian. In Graeco-Roman times, it was called Apollonopolis Parva or Apollinopolis Mikra (Greek: Ἀπόλλωνος ἡ μικρά; Ἀπόλλων μικρός), or Apollonos minoris.
