What Is an Island?
An island is an area of land that is surrounded entirely by water. That definition is quite simple to understand, but it comes with some caveats.
What Is Not Considered an Island (For Our Purposes)
An island is not a continental landmass. After all, the major continental landmasses of Oceania, the Americas, or Afro-Eurasia are much larger than and particular island on its own. That is why we are going to separate the list and only look at islands that are nations rather than continents. However, the largest landmasses would be the following in order: With that settled, we can now take a close look at the largest islands that exist around the world today.
The 15 Largest Islands in the World
The islands on this list range from 42,458 miles (about the size of Mississippi) to 822,720 miles (larger than Alaska). In addition, you might be surprised how populated some of these islands are. One even has close to 150 million people on it! Let’s dive in to each island from 15th largest to first.
15. Luzon
The island of Luzon is the largest one in all of the Philippines. This is also the most populous island in the entire nation, and it’s part of a major island group that includes many people and ethnic groups. This island is the fourth most populous one in the world, and it has many cities including the capital city of Manila. The island is located in Southeast Asia.
14. North Island
Te Ika-a-Maui is the official name of the North Island in New Zealand. The nation is split into two large islands and then several hundred smaller ones. Despite being smaller than the South Island by a fair margin, this island houses many more people compared to the other. New Zealand’s capital, Wellington, is located on this island along with several other cities and urban areas.
13. Java
The Indonesian island called Java is the island with the greatest population with over 140 million people calling this area home. The island is home to over 50% of the country’s entire population. Java is home to volcanoes, lush forests, and plains, making it ecologically unique. The island is a cultural and religious melting pot that features people with many beliefs such as Buddhism, Shaivism, and Islam.
12. South Island
The South Island of New Zealand is larger than the North Island, but it is not nearly as populous. The official name of this island is Te Waipounamu. This island is a popular tourist attraction owing to the amazing ski areas and its settings in the Lord of the Rings series. The island is filled with national parks and protected areas that are beautiful or culturally significant.
11. Sulawesi
Sulawesi is one of the four Greater Sunda Islands that are located in Indonesia. This island is highly populated with over 19 million people living throughout the land. The land is home to Mount Tongkoko, a volcano, a volcano that has been dormant for centuries. The island continues to gain new citizens and contains about 7% of the population of Indonesia.
10. Ellesmere Island
Canada’s Ellesmere Island is the island located furthest north in the country. Although it is the 10th largest island in the world, it’s only slightly smaller than Great Britain. Although it’s quite large, the island is only home to about 200 people due to its harsh environment. The northernmost settlement in the world is called Alert, and it’s located on this island although it is not used as a military base any longer.
9. Great Britain
Great Britain is a large and highly populated island that is located off the northwest coast of continental Europe that houses most the United Kingdom. This island is believed to have been connected to continental Europe until about 8,000 -10,000 years ago. Great Britain is the world’s third most populous island in existence today, and its population is still on the rise.
8. Victoria Island
Victoria Island is another large island that is located in Canada. Like Ellesmere Island, this one is very sparsely populated with only 2,162 people living on it. The island was named for Queen Victoria, and it’s somewhat shaped like a maple leaf, a symbol for Canada. The island is very far north in the Arctic Archipelago, and it’s close to the Northwest Territories of Canada.
7. Honshu
Honshu is the island in Japan with the highest population of people, totaling over 100 million individuals and over 80 percent of the total population. Honshu is home to Tokyo as well as many other large cities and prefectures. The area is known for its amazing infrastructure that allows so many people to live and thrive in the area. Also, the island is getting bigger due to land reclamation projects happening.
6. Sumatra
The island of Sumatra is another large island located in Indonesia. The island is interesting because of its amazing rainforests and unique animal species like the Sumatran Tiger and Sumatran Elephant. Unfortunately, this area has undergone severe deforestation that has led to many animal species becoming extinct in recent years.
5. Baffin Island
Baffin Island is the largest island in Canada, and it’s very far north. This island is home to many polar bears and ringed seals as well as nesting birds. The island is also home to people that work on the island in places such as iron mines. The small population of people on the island, just 13,000, is mostly Inuit individuals.
4. Madagascar
Madagascar is an island off the east coast of Africa’s Mozambique. The large island is home to over 27 million people. This land has many different geological areas that include mountains, plains, lowlands, marshes, and more. The island is home to many plants and animals, some that are found in a few other places in the world. However, the island is facing severe environmental problems in the form of flooding, erosion, and pollution.
3. Borneo
Borneo is a very interesting country because it is divided into space into three different countries. Malaysia, Brunei, and Indonesia each own part of this island. As such, the area is very diverse in terms of social and cultural elements. The island contains some of the oldest rainforests in the entire world, and those rainforests are home to many animals like the Bornean orangutan. The biodiversity of Borneo is simply immense, and many species of plants and animals thrive on this island.
2. New Guinea
The island of New Guinea is also divided between two countries. Namely, Indonesia and Papua New Guinea each control roughly half of the island. This island is the second-largest one in the entire world, and it has a large population to match with some 14 million people living here. New Guinea has incredible biodiversity as well as unique settlements of people living on it.
1. Greenland
Greenland is the largest island in the entire world. Although it’s the biggest island, it technically belongs to a much smaller country, Denmark. Despite the size difference, Greenland has fewer people than Denmark with 56,000 people compared with Denmark’s 5.8 million people. With their sizes combined, Greenland helps diminutive Denmark rank twelfth for the largest country in the world.
How Many People Live on Islands in the World?
About 730 million people, over 10% of the world’s population, currently live on islands. Although some people might think that islands are small or sparsely populated, the truth is that they are widely populated by many people. Java is the most populated island in the entire world, with a population that exceeds 147 million people despite the island only being the 13th largest island in the world. That should give you some insight into how large the island is and how many people live in a relatively small space.

Final Thoughts on the Largest Island in the World
Greenland is the largest island in the world, but it’s sparsely populated compared to many other islands that exist. With a mere 56,000 people living in this province of Denmark and over 147 million living on Java, it’s clear that size isn’t the only indicator of an island’s significance. All in all, even though these islands are very large, they pale in comparison to the size of other major landmasses. That just shows how very large the Earth is and how much of the area humans have to live in. Some of the most beautiful islands in the world include:
Bora Bora: An island where coral reefs form a barrier and create a crystalline lagoon. Bora Bora is famous for its huts that sit directly on the water.Vancouver Island: Home to two resident pods of orca whales and the densest concentration of cougars in the world.Palawan: A Philippine island that’s home to a large underground river and many coral reefs, sandy beaches, and diverse ecoregions.
