Osijek is the fourth largest city in Croatia (Europe) with a population of 114,616 in 2001. It is the largest city and the economic and cultural centre of the eastern Croatian region of Slavonia, as well as the administrative centre of Osijek-Baranja county. Osijek is located on the right bank of the river Drava, 25 kilometres (16 mi) upstream of its confluence with the Danube, at an elevation of 94 metres (310 ft).
The name was given to the city due to its position on elevated ground which prevented the city being flooded by the local swamp waters. Its name Osijek comes from the Croatian word "oseka" which means "ebb tide".
