Can you name the ten largest lakes on Earth? This quiz ranks lakes by surface area — the sheer footprint of water, not depth or volume. That single choice shapes the whole list, because the biggest lake by area is more than four times the size of the runner-up.
It's a great starter for geography fans: a few answers are famous, a few sit in places most people never think about, and North America shows up far more often than you'd expect. If you can find five without help, you're doing well.
How to play
Each lake is pinned on the map from the start — the pins are location hints, so you know where to look but not what it's called.
Just start typing; the answer bar focuses itself and matches as you type.
Spelling is forgiving: common short forms are accepted, and you don't need to type the word "Lake".
The timer counts up from zero — name all ten as fast as you can.

What counts in this quiz
Exactly 10 lakes, ranked by surface area in square kilometers.
The Caspian Sea counts as a lake here — despite the name, it is completely landlocked with no outlet to the ocean, which is what makes a lake a lake. At roughly 371,000 km² it takes the top spot.
Lake Michigan and Lake Huron are counted as two separate lakes, the conventional treatment — even though they connect at the Straits of Mackinac and are technically one body of water hydrologically.
What's not included — and why
The Aral Sea is out — it was once the fourth-largest lake in the world, but decades of river diversion shrank it to a fraction of its former size, dropping it far below the top 10.
Deep-but-narrow lakes ranked by volume would look very different — this list is strictly surface area, so depth wins you nothing.
Good to know
Lake Baikal in Siberia is the deepest lake on Earth (over 1,600 m) and holds about 20% of the world's unfrozen fresh surface water — more than all the North American Great Lakes combined.
Canada wholly contains two entries in the top 10 — Great Bear and Great Slave — and shares two more with the United States.
The Caspian Sea is so large it has its own sturgeon fishery, shipping lanes, and five countries on its shores.
