The Sava is a major river in Central and Southeast Europe.

It serves as the longest tributary of the Danube River. A tributary is a river that flows into a larger main river. The Sava is unique because it is the largest tributary of the Danube by water volume.

It is also the second-largest after the Tisza in terms of length and catchment area. The catchment area is the total land from which the river collects its water. The river drains a large part of the Dinaric Alps region. It is joined by many important tributaries, including the Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut, and Krka.

The river begins in northwest Slovenia from two distinct headwaters.

The first is the Sava Dolinka, which rises at the Zelenci Pools. This spring is fed by groundwater near the Slovene-Italian border. The second is the Sava Bohinjka, which starts near Lake Bohinj. Some sources say the Sava Bohinjka begins at the Savica Falls. These two branches flow east to Radovljica. At this confluence, the two streams meet and become the Sava River.

From Radovljica, the water flows southeast toward the Ljubljana Basin.

As the Sava moves through Slovenia, it interacts with human engineering. The river encounters several hydroelectric dams and reservoirs. These include the Moste plant and the Lake Trboje and Lake Zbilje reservoirs. The river also flows through the capital city of Ljubljana. Near the city, there is a reservoir next to the Tacen Whitewater Course.

After leaving the Ljubljana Basin, the river enters the Sava Hills. It passes through the Central Sava Valley, which contains mining towns like Trbovlje. The river also provides water for the Krško Nuclear Power Plant to dissipate heat.

The Sava's path through Croatia and Bosnia and Herzegovina is very complex.

In Croatia, the river flows through Zagreb. Near the city, the landscape includes forests, marshes, and lakes in gravel pits. The Sava–Odra flood-relief canal was built near Zagreb to control flooding. This was done after a destructive flood in 1964 killed 17 people. Further downstream, the river becomes a border between Croatia and Bosnia and Herzegovina. It flows past towns like Slavonski Brod and Brčko. In these areas, the river meanders through wide plains and wetlands.

History and language provide deep connections to the river's identity. The name Sava likely comes from a Proto-Indo-European root meaning "that which waters the ground." Ancient Greeks called the river the Saos. The Romans used the name Savus. A Greek writer named Strabo also used the name Noarus for parts of the river. The river has long served as a political boundary. It marks the border between different regions and countries. Before 1991, it was the longest river entirely within Yugoslavia. Today, it continues to act as an international frontier between several nations.

The river basin is home to a very large population. It is estimated that 8,176,000 people live within the Sava River basin. The river is connected to three different capital cities. These are Ljubljana, Zagreb, and Belgrade.

Belgrade is the largest city in the basin, with an urban population of over 1.1 million people. The river also supports diverse ecosystems like the Lonjsko polje Nature Park. This park contains marshes that are frequently flooded by the river.

Navigation and geography define how people use the Sava today.

The river is navigable for larger vessels starting from Sisak. However, navigation can be difficult. There are issues with narrow fairways, bridge clearances, and sunken objects. Some of these objects include unexploded ordnance from past conflicts. In Serbia, the river flows through the province of Vojvodina and Central Serbia. It forms large islands, such as Ada Ciganlija in Belgrade.

Finally, the Sava reaches its end at the Great War Island.

There, it discharges its waters into the Danube River.
