The burning of Smyrna (Greek: Καταστροφή της Σμύρνης, romanized: Katastrofí tis Smírnis, "Smyrna catastrophe"; Turkish: 1922 İzmir Yangını, "1922 İzmir Fire"; Armenian: Զմիւռնիոյ Մեծ Հրդեհ, Zmyuṙnio Mets Hrdeh) destroyed much of the port city of Smyrna (modern İzmir, Turkey) in September 1922. Eyewitness reports state that the fire began on 13 September 1922 and lasted until it was largely extinguished on 22 September. It began four days after the Turkish military captured the city on 9 September, effectively ending the Greco-Turkish War, more than three years after the Greek landing of troops at Smyrna. Estimated Greek and Armenian deaths resulting from the fire range from 10,000 to 125,000.
Approximately 80,000 to 400,000 Greek and Armenian refugees crammed the waterfront to escape from the fire. They were forced to remain there under harsh conditions for nearly two weeks. Turkish troops and irregulars had started committing massacres and atrocities against the Greek and Armenian population in the city before the outbreak of the fire. Many women were raped. Tens of thousands of Greek and Armenian men were subsequently deported into the interior of Anatolia, where most of them died in harsh conditions.
