Lake Dubrava (Croatian: Dubravsko jezero) is a reservoir on the Drava in northern Croatia.

[1] The Drava flows into the reservoir near the town of Prelog, while the dam is located near the village of Sveta Marija.

[3] The town of Prelog is the only settlement on the shores of the lake, with other nearby villages including Otok, Oporovec, Donji Mihaljevec and Sveta Marija in Međimurje County, as well as Hrženica and Struga in Varaždin County.

Lake Dubrava takes its name from the village of Donja Dubrava, which is located next to the place where the lake's outflow canal meets the natural flow of the Drava, around 6 kilometres from the dam.

Near the town of Prelog, there is also a small marina on the lake, with a number of log cabins and a small airfield for powered hang gliders on the shores of the Drava nearby.
