Osijek field) is an old name created in the first years of the 18th century, the area that included the entire area around the city of Osijek and the region between the lower course of the Drava and Danube river and practically whole flow of the river Vuka.

[1] Because Osijek field lies on the border of Syrmia, Baranja and Slavonia, it was added, sometimes to one and sometimes to the other of three neighboring Eparchies, while sometimes it had its own bishop.

Patriarch Arsenije IV Jovanović Šakabenta handed Eparchy of Osječko polje in 1746 to his Bishop Jovan Georgijević.
