- A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term “country” may refer to a sovereign state, states with limited recognition, constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of “countries” in the world since several states have disputed sovereignty status, limited recognition and a number of non-sovereign entities are commonly called countries.
