Which lake has the largest surface area on Earth?

Quick Answer

The Caspian Sea is the largest lake on Earth by surface area, at about 371,000 square kilometres.

The Full Story

The Caspian Sea is technically a lake, not a sea, and it is the largest inland body of water on Earth by surface area. It covers about 371,000 square kilometres and borders five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. Its size, salinity, and isolated geography make it a unique lake ecosystem. Because it is endorheic, water enters it but does not flow out to the oceans.
