An archipelago sometimes called an island group or island chain is a chain or cluster of islands.

Archipelagos may be found isolated in bodies of water or neighbouring a large landmass. Indonesia is the world’s largest archipelago with over 13,000 islands & totals around 18,000 islands.

The Malay Archipelago (or Indonesian Archipelago) is often referred to as the largest archipelago in the world, but this is meant by area rather than a number of islands.

This title aptly represents its 25,000 - 30,000 or so islands which span 5,400 kilometres eastward from Sabang in northern Sumatra to Merauke in Irian Jaya (now known as Papua).
