Syrmia ((セルビア語:Срем, ''Srem''); (クロアチア語:Srijem)) is a fertile region of the Pannonian Plain in Europe, between the Danube and Sava rivers. It is divided between Serbia in the east and Croatia in the west. Most of Syrmia is located in the Srem and South Bačka districts of Serbia's Autonomous Province of Vojvodina. A smaller part of the region around Novi Beograd, Zemun, and Surčin belongs to the City of Belgrade. The westernmost part is in eastern Croatia in Vukovar-Srijem.
Syrmia has been a part of the Roman Empire, the Hun Empire, the Ostrogothic Kingdom, the Gepid Kingdom, the Lombard state, the Byzantine Empire, the Avar Khaganate, the Frankish Empire, the Bulgarian Empire, Pannonian Croatia, the Kingdom of Hungary, the Ottoman Empire, the Habsburg Monarchy, the Austrian Empire, Austria-Hungary, the State of Slovenes, Croats and Serbs, the Kingdom of Serbia, the Kingdom of Serbs, Croats and Slovenes, the Kingdom of Yugoslavia, and the Socialist Federal Republic of Yugoslavia which, upon advice from the Ðilas Commission, assigned the eastern part of the region to the Federated Republic of Serbia and the western part to the Federated Republic of Croatia in 1945. The westernmost part of Syrmia is in eastern Croatia in Vukovar-Srijem, while the majority of Syrmia is part of Republic of Serbia.
Today, the name ''Srijem'' is used in the standard Croatian language to designate the region, whereas both ''Srem'' (Cyrillic: ''Срем'') and ''Srijem'' (Cyrillic: ''Сријем'') are used in the two standard varieties of Serbian. Other names for the region include:
