Which Country Has No Flag?

Every recognised country has a flag — but some territories, regions, and entities are more complicated. The full answer.

Every sovereign nation recognised by the United Nations has an official national flag. However, some territories and disputed regions are more complex. Antarctica has no official flag because it has no government — though the True South flag has been proposed. Some nations like Nepal have non-rectangular flags (a double pennon). The Vatican uses a square flag rather than the universal rectangle. Disputed territories like Kosovo, Western Sahara, and Taiwan have flags that are not universally recognised. The most unusual national flag in terms of design belongs to Nepal — the only non-rectangular national flag in the world.
