Largest Lakes in the World

Updated September 9, 2022 | Infoplease Staff

You'd think it was the ocean

A lake is defined as a body of water surrounded by land, separate from any surrounding rivers or outlets, that is not the ocean. There is no limit on size or salinity. These are the only criteria we've chosen for determining our rankings. As a result, the Caspian Sea is the world's largest lake by area and by volume; at more than 5 times the size of the next largest lake, it truly deserve the designation "sea".

If we restrict the rankings to fresh bodies of water, we get two different results. By volume of water, the world's largest lake is actually Lake Baikal in Russia. The world's deepest lake has a proportionally large volume. We are ranking by their surface area. By this metric, the largest freshwater lake would be Lake Superior in the U.S. Lake Huron, another of the Great Lakes, is also in the Top 5.

The following table lists the large lakes of the world according to size and including information such as name, location, area, length, and depth. Read on to learn more.

1. The Caspian Sea is called “sea” because the Romans, finding it salty, named it Mare Caspium. Many geographers, however, consider it a lake because it is land-locked.
2. Figures represent high-water data.
3. Varies with the rainfall of the wet season. It has been reported to dry up almost completely on occasion.
