Island Countries — Countries With No Land Borders

Island countries are sovereign nations entirely surrounded by water, with no land borders shared with other countries. These nations range from massive landmasses like Australia and Madagascar to tiny atolls in the Pacific. Island nations face unique challenges including vulnerability to rising sea levels, dependence on maritime trade, and often limited natural resources. However, many have thrived thanks to tourism, fishing, and strategic geographic positions.
