Headline finding

Canada leads the world for countries with the largest lake area at 891,163 km² of inland water.

What the numbers show

Canada's lead at the top of this ranking is 23.7% above the second-place country — comfortable but not insurmountable — a credible challenger could plausibly close that gap over a decade.

The five countries leading the table — Canada, Russia, United States, India, China — together set the global benchmark. The next 20 countries fill the rest of the table, with Iran anchoring the list at 12,000.

Figures are drawn from CIA World Factbook 2024. We use this source because it produces a single, internally consistent dataset rather than aggregating from national statistics offices, which makes year-on-year comparison reliable. The next update is expected when the source publishes its next annual release — see the methodology section below for which year of data is currently shown.

Coverage
Top 25 countries shown. Full source dataset covers all 195 sovereign states where data is available.
Refresh cadence
Updated annually as the source publishes new figures, typically autumn or spring.

Country definitions follow the source: where the UN, the World Bank and the CIA Factbook disagree on borders or recognition, we use the figure as published rather than reconciling between bodies. Comparisons across rankings should be made with this in mind.
