The Lesser Sunda Islands consist of two geologically distinct archipelagos. Outside the city lies the archipelago of Karlskrona, the most southern of the Swedish archipelagos. Okinawa's inhabited islands are typically divided into three geographical archipelagos. Geographically, the Austral Islands consist of two separate archipelagos. The Norwegian mountains plunge into the sea creating deep fjords and archipelagos. Lake Victoria has numerous archipelagos, or groups of islands.

A 2007 inventory estimates that the Galician coast has 316 archipelagos, islets, and freestanding rocks. The continent includes Madagascar and various archipelagos. The Madeira and Azores archipelagos have a narrower temperature range. There are various small archipelagos within the Outer Hebrides. Ko Samet is one of the driest archipelagos in Thailand. High levels of genetic structure occurring across the archipelagos indicate an isolation by colonization pattern. The very different geologies of the two archipelagos have resulted in dissimilar local economies.
