The first one in Top 10 Longest Rivers in Belarus that Toplist would like to introduce to you is Dnieper. The Dnieper is a major European river that begins in the Valdai Hills near Smolensk, Russia, and flows through Belarus and Ukraine to the Black Sea. It is the longest river in Ukraine and Belarus, as well as the fourth-longest river in Europe, after the Volga, Danube, and Ural. The total length is about 2,201 km (1,368 mi), with a drainage basin of 504,000 square kilometers (195,000 sq mi).

The river was once a part of the Amber Road trade routes. During The Ruin, the area was contested by the Polish–Lithuanian Commonwealth and Russia, dividing Ukraine into right and left bank areas. During the Soviet era, the river was known for its large hydroelectric dams and reservoirs. The 1986 Chernobyl disaster occurred on the Pripyat, just above its confluence with the Dnieper. The Dnieper is an important navigable waterway for Ukraine's economy, and it is linked to other waterways in Europe by the Dnieper–Bug Canal.

The river's total length is variously given as 2,145 km (1,333 mi) or 2,201 km (1,368 mi) of which 485 km (301 mi) are in Russia, 700 km (430 mi) in Belarus, and 1,095 km (680 mi) in Ukraine. Its basin spans 504,000 square kilometers (195,000 square miles), with 289,000 km2 (112,000 sq mi) in Ukraine and 118,360 km2 (45,700 sq mi) in Belarus.

The Dnieper River's headwaters are the sedge bogs (Akseninsky Mokh) of the Valdai Hills in central Russia, at an elevation of 220 meters (720 ft). It forms the border between Belarus and Ukraine for 115 kilometers (71 miles). Its estuary, or liman, was once guarded by the powerful fortress of Ochakiv.

Belarus's southernmost point is Brahin Raion on the Dnieper, south of Kamaryn.

Length: 2,201 km (1,368 mi)

The second one in Top 10 Longest Rivers in Belarus that Toplist would like to introduce to you is Daugava. The Daugava River rises in Russia's Valdai Hills and flows through Belarus and Latvia into the Baltic Sea's Gulf of Riga. It rises near the Volga's headwaters. It is 1,020 km (630 mi) long, with 325 km (202 mi) in Russia. It is a westward-flowing river that forms a large curve to the south, passing through northern Belarus.

Riga, Latvia's capital, spans the estuary four times, lying on both banks, with the city center 15 kilometers (9.3 miles) from the mouth and serving as a significant port. The river's total catchment area is 87,900 km2 (33,900 sq mi), of which 33,150 km2 (12,800 sq mi) is within Belarus.

The river's environment began to deteriorate during the era of Soviet collective agriculture (which produced significant adverse water pollution runoff) and a wave of hydroelectric power projects. The Daugava River is considered moderately polluted in Belarus, with the main sources being treated wastewater, fish farming, and agricultural chemical runoff (e.g. herbicides, pesticides, nitrate and phosphate).

Length: 1,020 km (630 mi)

The third one in Top 10 Longest Rivers in Belarus that Toplist would like to introduce to you is Neman. The Nemunas, also known as the Nioman, Neman, or Memel, is a river in Europe that originates in central Belarus and flows through Lithuania before forming the northern border of Kaliningrad Oblast, Russia's western exclave, which specifically follows its southern channel. It drains into the Curonian Lagoon, which is only tenuously connected to the Baltic Sea. It has a length of 937 kilometers (582 miles) and is considered a major Eastern European river. It flows generally west to Grodno, about 12 kilometers (7.5 miles) from the Polish border, then north to Kaunas and west again to the sea.

Perch, pike, zander, roach, tench, bream, rudd, ruffe, and bleak have all been caught. Stone loach, three-spined stickleback, minnows, trout, sculpins, gudgeon, dace, and chub have been caught in its tributaries.

Atlantic salmon migrated upstream to spawn, but dams on the river, the majority of which were built in the twentieth century, depleted them. There are no fish ladders on the Kaunas dam. The spawning season occurred in the fall. According to ethnographic studies conducted prior to the dams, night fishing with torches and harpoons was a common technique.

Length: 937 km (582 mi)

The fourth one in Top 10 Longest Rivers in Belarus that Toplist would like to introduce to you is Bug. The Bug is a major river in Eastern Europe that flows through Belarus, Poland, and Ukraine. It is 774 kilometers long (481 mi).

The Bug is a Narew tributary to the left. It flows from the Lviv Oblast in western Ukraine northwards into the Volyn Oblast, then into Poland, where it follows part of the border between the Masovian and Podlaskie Voivodeships. It merges with the Narew at Serock, a few kilometers upstream of the man-made Zegrze Lake.

This section of the Narew between the confluence and the Vistula is sometimes referred to as the Bugo-Narew, but on December 27, 1962, the Prime Minister of Poland's act abolished the name "Bugo-Narew," shortly after the completion of Zegrze Lake.

The westernmost point of Belarus is located on the Bug, a few kilometers from Vysokaye in the Kamenets District of the Brest Region. The Dnieper-Bug Canal connects it to the Dnieper via the Mukhavets, a right-bank tributary.

The Neris River originates in northern Belarus. It flows westward, passing through Vilnius (Lithuania's capital), and as its main tributary, it flows into the Nemunas (Neman) at Kaunas in the country's south-central region. It is 510 kilometers long (320 mi). The river flows through Lithuania for 235 kilometers (146 miles) after passing through Belarus for 276 kilometers (171 miles). It is the eighth longest river in Belarus.

The Neris River connects the Lithuanian capitals of Kernav and Vilnius. Along its banks are pagan Lithuanian burial grounds. Karmazinai's old burial mounds, with many mythological stones and a sacred oak, are located 25 kilometers (16 miles) from Vilnius.

Neris is a Baltic name, a cognate of the Lithuanian nerti, which means "to dive, swim downstream" as well as "to net, crochet." In the beginning, the name most likely had a more general meaning of "flow" or, more specifically, "swift and swirling flow".

The name is etymologically related to a class of hydronyms found throughout the modern and prehistoric Baltic ranges, such as Lithuanian Narotis, Narasa (rivers), Narutis (lake), Old Prussian Narus, and Nara near Moscow. These are related to the Lithuanian words narus, which means "deep," and nerti, which means "to dive."
