When it comes to the sheer number of islands a country possesses, you might instinctively think of a tropical archipelago or a nation scattered across the high seas. The reality, however, is far more surprising: the country with the most islands is not a tropical nation at all.
Counts vary depending on the criteria used—whether an island must be permanently above sea level, be naturally formed, or have a permanent population. Even with these differences, a few countries stand out for their staggering numbers of islands, ranging from tiny, uninhabited rock outcrops to bustling urban centers.
Sweden tops the list with more than 267,000 islands. While the vast majority are uninhabited, the Stockholm Archipelago alone boasts thousands of offshore islands. Many of these are popular for tourism, recreation, and wildlife conservation.
Norway’s rugged coastline is dotted with approximately 239,057 islands. These include offshore islands, fishing communities, and isolated islets that line the fjords and the Arctic Circle.
Finland follows closely with nearly 180,000 islands, especially in its eastern regions and inland waterways. The country’s lakes host countless small islands, some visible only on detailed survey maps.
Canada’s islands total over 50,000, ranging from the world‑class Baffin Island to thousands of small offshore and inland islands. Many are seasonally accessible and face changing conditions due to climate change.
Indonesia’s archipelago contains roughly 17,500 islands, including major landmasses like Java, Sumatra, and Bali. The islands vary from densely populated urban centers to uninhabited islets.
The United States spans thousands of islands across its mainland and territories—from the Aleutian chain and Great Lakes islands to the Hawaiian archipelago and Caribbean territories such as Puerto Rico and the U.S. Virgin Islands.
Japan’s island count was revised from an estimated 6,800 to over 14,000 following a comprehensive survey by the Geospatial Information Authority of Japan. The updated figure reflects more precise mapping and stricter island criteria.
While Australia’s mainland is a continent, its jurisdiction includes thousands of offshore islands, including Tasmania and various Antarctic dependencies. External territories such as Christmas Island and Norfolk Island increase the total when counted.
The Philippines has more than 7,600 islands, with Luzon and Mindanao among the largest and most populous. The number of inhabited islands fluctuates, especially in low‑lying areas vulnerable to sea‑level rise.
The United Kingdom comprises numerous islands, from the main islands of Great Britain and Ireland to countless offshore islets. Including overseas territories further raises the count, though some islands are at risk of erosion.
These figures illustrate that the country with the most islands is a Northern European nation rather than a tropical archipelago, highlighting the diversity of island geographies around the globe.
