The Istanbul nostalgic tramways are two heritage tramlines in the city of Istanbul, Turkey. The city has two completely separate heritage tram systems, one on the European side, the other on the Asian side.

Heritage streetcars or heritage trams are a part of the efforts to preserve rail transit heritage. In addition to preserving street-running rail vehicles, heritage streetcar operations can include upkeep of historic rail infrastructure. Working heritage streetcars are closely related to the growing global heritage railway movement and form a part of the living history of rail transport.
