Country or territory (Territories without full sovereignty[1] in italics)

abThe concept of
state sovereignty is somewhat imprecise and there are disagreements about whether certain territories are sovereign. There are currently
195 states that are generally regarded as "fully" sovereign: this includes the
193 member states of the
United Nations plus the observer states of
Vatican City and the
State of Palestine. Some of these states have under their jurisdiction
territories, dependencies, or collectivities that are clearly non-sovereign geographical areas. These territories are generally regarded as being subsumed within the overarching sovereignty of the governing state. For example, the
United Kingdom holds sovereignty over the territory of
Gibraltar, even though Gibraltar is not considered to be part of the United Kingdom. There are a few territories in the world that are neither clearly sovereign nor clearly subsumed under another state's sovereignty. Often, these territories have declared themselves to be sovereign, but they are either not widely recognized as such or lack some of the necessary conditions for sovereign statehood. In these cases, explanatory footnotes indicate how the territory is treated for the purposes of this list.

abThis territory is not sovereign, but is a country within the
Kingdom of Denmark. For purposes of this list,
Denmark, the
Faroe Islands, and
Greenland are considered constituent parts of one sovereign state.

abThis territory is not sovereign, but is an
overseas collectivity of
France, and as such it is part of the sovereign territory of France.
^This territory is not sovereign, but is an
insular area of the United States.
U.S. territories are considered to be part of the sovereign territory of the United States.
