The Neman, Nemunas, Nyoman, Niemen or Memel, a major Eastern European river, rises in Belarus and flows through Lithuania before draining into the Curonian Lagoon, and then into the  Baltic Sea at Klaipeda. It begins at the confluence of two smaller tributaries (map coordinates 53.348194,27.108377), about southwest of the town of Uzda in central Belarus, and about southwest of Minsk. In its lower reaches it forms the border between Lithuania and Russia's Kaliningrad Oblast. It also, very briefly, forms part of the border between Lithuania and Belarus. The fourteenth-largest river in Europe, the largest in Lithuania, and the third-largest in Belarus, the Neman is navigable for most of its length.
