Arctic sea ice has polar bears, walruses, and seabirds that look a lot like penguins. What it does not have is wild penguins.
All 18 currently recognized living penguin species are found in the Southern Hemisphere. Their range runs from Antarctica and the subantarctic islands all the way to the Galapagos Islands near the equator. On the map, once you cross north of the equator, that line stops.
The mismatch is easy to confuse because the North Atlantic really did once have a black-and-white, not-very-flying seabird called the great auk. Its upright posture looked much like a penguin, and in English the word penguin was often used for it early on.
The problem is that the great auk belonged to the auk family, followed a different evolutionary path from penguins, and became extinct in 1844. Today, a black-and-white bird seen in the Arctic Circle is more likely to be a puffin, an auk, or another seabird. It will not be a penguin.

What about penguins you see in Northern Hemisphere zoos? They are real penguins, of course, but they are Southern Hemisphere birds being cared for by people in the north. Geographic distribution and zoo display are two different things.
You can see penguins in zoos in Taipei, Japan, Europe, and the United States. But the wild Arctic Circle is not going to produce emperor penguins, king penguins, or little blue penguins on its own. That line is very clean.
Polar bears and penguins often get placed together on the same cartoon poster.
In reality, they do not meet in the wild at all.
One keeps to the icy sea at the far north of the planet. The other lives along Southern Hemisphere coasts and islands. Even the direction is opposite.
Keep that in mind, and your map of penguins becomes much clearer.
Penguins belong to the ocean world of the Southern Hemisphere; cold is only part of the story.
Change the direction, and the whole story changes.
FAQ
Why are there no penguins in the Arctic?
All 18 currently recognized living penguin species evolved and are distributed in the Southern Hemisphere. In the Northern Hemisphere, similar ecological space is occupied by seabirds such as auks, so the Arctic Circle has no native penguin population.
Are puffins or great auks penguins?
Puffins and penguins belong to different bird families. The great auk also looked very penguin-like, but it belonged to the auk family and went extinct in 1844.
Are penguins in Northern Hemisphere zoos real penguins?
Yes. They are real penguins cared for by people in the north, but zoo display is different from native wild distribution.
