The Verknė (known as Galaverknė in the upper reaches; Polish: Wierzchnia) is a 77-kilometre (48 mi) stream in Lithuania. It is a right tributary of the river Neman (Nemunas); their confluence is 3 km (1.9 mi) north of Birštonas.

Its spring is near Rūdiškės in the Trakai District Municipality where it is known as the Galaverknė and passes a chain of smaller lakes. Having left the Vilkokšnis lake, the stream is known as the Verknė. Aukštadvaris with a population of 977 (2011) is the only relatively large settlement along the river. The Verknė passes the Prienai District Municipality and forms the border of the Birštonas Municipality near its mouth.

In 1960, the Verknė was impounded to create two reservoirs with hydroelectric power stations. The larger of the two is Aukštadvaris Reservoir (2.93 km2 (1.13 sq mi); the smaller one being Jundeliškės Reservoir.
