This river is a vital part of the landscape. It drains into the Curonian Lagoon. This lagoon is narrowly connected to the Baltic Sea. The river is the largest in Lithuania. It is also the third-largest in Belarus.

The river begins in central Belarus. It starts from two small headwaters. These waters merge southwest of the town of Uzda. This is near the capital city, Minsk. From there, the river flows west to Grodno. It then flows north to Kaunas. Finally, it flows westward toward the sea.

A stretch of the river forms the border between Lithuania and Russia's Kaliningrad Oblast. The river follows the southern channel of this border.

The Neman is a very old river. Its drainage basin formed during the late Quaternary period. This was near the edge of the last glacial sheet. Scientists date this to about 25,000 to 22,000 BC. The river valley is now very wide and deep. The river itself is quite slow. It flows at a speed of about 0.5 meters per second. The total length of the river is 907 kilometers.

It is the fourth longest river in the Baltic Sea basin.

The river has many parts and tributaries. It has about 105 first-class tributaries. The largest of these are the Neris, the Shchara, and the Šešupė. Fifteen of these tributaries are longer than 100 kilometers. The Nemunas basin in Lithuania covers 72% of the country's territory. It drains more than 20,000 rivers and rivulets.

The river's depth changes along its course. It is shallower in the upper parts and deeper in the lower basin. Its greatest depth is 7 meters. At its widest, it extends about 1,200 meters.

There are unique shapes in the river's path. In the Punia forest, the river makes large loops. These are called the Nemunas loops. These are not regular meanders. Instead, they follow underlying tectonic structures. Tectonic structures are deep faults in the Earth's crust. These faults are also the source of local mineral springs.

Near Prienai, the river makes a loop shaped like a teardrop. The river flows along a double bend between Balbieriškis and Birštonas. This section is 40 kilometers long.

The river has a long history with many famous people. In 1807, Napoleon and Tsar Alexander I signed the Treaty of Tilsit. They signed it on a raft on the river. In 1812, Napoleon's army crossed the Neman. This was the start of the French invasion of Russia.

In the past, castles along the river defended against Teutonic knights. The river is also part of the Neman Culture. This was a Neolithic archaeological subculture.

Humans use the river for many important tasks. It provides water for industry and agriculture. It is used for fishing and recreation. In 1959, a dam was built near Kaunas. This created the Kaunas Reservoir. It is the largest lake in Lithuania. The reservoir is 44 kilometers long. It is a popular place for yachting.

The river is a home for many animals. Many fish live in the water. These include perch, pike, zander, and bream. Atlantic salmon used to migrate upstream to spawn. However, modern dams have made this harder. The river also feeds the Curonian Lagoon. It provides the main inflow of water to the lagoon. This keeps the water almost fresh. This helps both fresh and brackish water animals survive.
