Two North American Countries Located on Islands: Bahamas and Cuba

The two sovereign nations in North America that are entirely situated on islands are:

1. The Bahamas – An archipelago of 700+ islands and cays in the Atlantic, north of Cuba and southeast of Florida.
2. Cuba – The largest Caribbean island, located south of the Bahamas, east of Mexico, and north of Jamaica.

Other island territories in North America (like Jamaica, Hispaniola, Puerto Rico) are either not sovereign (Puerto Rico is a U.S. territory) or share islands with other countries (Hispaniola: Haiti & Dominican Republic).
