The Agora of Smyrna, alternatively known as the Agora of İzmir (Turkish: İzmir Agorası), is an ancient Roman agora located in Smyrna (present-day İzmir, Turkey). Originally built by the Greeks in the 4th century BC, the agora was ruined by an earthquake in 178 AD. Roman Emperor Marcus Aurelius ordered its reconstruction. Excavations started in 1933. In 2020, the Agora of Smyrna became a Tentative World Heritage Site as part of "The Historical Port City of Izmir."
