There are around 900,000 islands worldwide. Norway and Sweden have approximately 230,000 each, while Japan and Chile have about 6,000 each.

Islands hold their own special allure and appeal. After all, who hasn’t dreamt of their very own island getaway? No wonder everybody wants to know what the smallest islands in the world are. It is also the reason why you’re reading this article, right? So, here’s a picture preview to help satisfy your curiosity:

Whether is a river, a lake, or a vast ocean, these islands all have interesting stories!

These are 15 examples of the smallest islands in the world. We cover everything from island nations to both inhabited and uninhabited islands. Then we’ll dive into some small islands that are notable for their small size.

The 15 Smallest Islands in the World

There are a lot of islands in the world, to say the least. Not all of them are discovered or documented. The definition of the concept doesn’t help either. Every piece of land that is surrounded by water is an island — quite ambiguous, right?

This is why it would be difficult to make a list of the actual smallest islands in the world. The smallest-smallest island might not even be discovered yet! In addition, what qualifies as an island is fluid — for instance, are small atolls barely poking above the water islands?

Below we’ll document a few contenders for the crown. One has been recognized by the United Nations while another island claims the title of the smallest inhabited island in the world.

1. Just Room Enough Island

This contender for the smallest island in the world is located in Saint Lawrence River. If you want more to do than just seeing Just Enough Room Island, it’s located in an island chain that contains 1,864 islands with plenty of hotels, campgrounds, and many other spots to soak up the summer sun and enjoy being on the water.

The smallest uninhabited island in the world, Simping Island, has only 1.23 acres. You might be wondering how amongst the 900,000 or so islands in the world that include tiny outcroppings this island can claim the title. The simple answer is its claim of being the smallest island in the world has been recognized by the United Nations. It is located on the northern outskirts of Singkawang city. Tour guides are available due to its popularity.

Coral reefs surround the small island. There’re also some trees on the island. Tourists can swim in the water, as it’s usually serene.
