The Chios expedition (Greek: Εκστρατεία της Χίου) was an unsuccessful attempt of the regular Greek army and irregular military units for the recapture of Chios island during the final stages of the Greek War of Independence. Chios had participated in the Greek uprising against the Ottoman Empire, but had been captured and its population massacred by the Ottoman fleet in 1822.
