Countries and Continents
Countries on the globe with their flags. Image: © kk nationsonline.org How many countries are there in the world?
A lot, and no, Nambia, Button, and Nipple are not among them. 
Anyhow, there are 193, 195, 237, 245, 248, or 253 countries in the world, depending on definition.
193 sovereign states are members of the United Nations, the world's largest intergovernmental organization. 
Today there are 195 recognized sovereign states on the planet, the two countries which are not members of the United Nations are Palestine
and Vatican City
(they are so-called observer states).
The IMF, the International Monetary Fund, lists on its "Country Data Profile" page 237 countries, without distinction, whether it is a sovereign country or a dependent territory. *
The United Nations' "UN/LOCODE Code List by Country and Territory" lists 248 countries and territories; the list also includes Antarctica. 
Not included in the IMF list, nor the United Nations list, are some country-like territories, geopolitical units that are de facto autonomous but disputed or otherwise not generally recognized, such as Abkhazia, Northern Cyprus, Saharawi (Western Sahara), Somaliland, and Transnistria, which would add five more countries to the list.
And there are nations that have their own territory and cultural identity but are part of a parent state entity, such as the American Indian nations of North America or the Uighurs in the autonomous region of Xinjiang, or Tibet; the former Tibetan Empire is now, not entirely voluntarily, an autonomous region of China.
There are other states or countries or country-like geopolitical entities that are not members of the UN. Besides sovereign nations, there are autonomous self-ruling political units that are part of a sovereign state but not part of the mainland, and there are self-ruling territories, but they are not or only partially recognized as such.
For example, Taiwan
(ROC), the island state off the southeast coast of China, with a functioning multi-party democracy and a population
of 23.6 million people, has an uncertain political status. Both the ROC and China (PRC) still officially (constitutionally) claim mainland China and the Taiwan Area as part of their territories.
Among the partially recognized states or state-like entities are Abkhazia, Kosovo, the Cook Islands, Northern Cyprus, Sahrawi Arab Democratic Republic (Western Sahara), Somaliland, and Transnistria. Dependent territories Dependencies
are territorial units that do not have full political independence or sovereignty; they are under the jurisdiction of a sovereign state such as France, the United Kingdom, or the United States, but are not formally annexed.
The probably best known dependent territories are Greenland
, the Faroe Islands
, Puerto Rico
, French Polynesia
, French Guiana
, Mayotte, Réunion
, New Caledonia
, the Falkland Islands, and Gibraltar. Countries by Continents Africa

The western portion of the Eurasian continent is known as Europe
. There are 44 sovereign countries, not included are countries that only have a small territory in Europe like Azerbaijan, Georgia, Kazakhstan, and Turkey. 43 European countries are members of the United Nations (Vatican City

There are no countries in Antarctica. There are no people in Antarctica apart from some personnel from research stations and field camps. A number of countries operate seasonal or year-round research stations on the continent and its surrounding islands. Population source: United Nations Transcontinental countries
Usually, the location of a country can be described by the continent on which it is located, but there are some countries with territories that extend across a continental border, such as Egypt, which is located in North Africa and Western Asia. Russia stretches over Eastern Europe and North Asia. Azerbaijan
, and Kazakhstan
extend partially into Europe, and Turkey
occupies a small portion of mainland Europe in East Thrace. Name Changes
There are some minor changes to earlier maps.
Three countries changed their names: Swaziland
is now Eswatini (eSwatini: Land of the Swazis),
the Former Yugoslav Republic of Macedonia
finally became North Macedonia, and
the Czech Republic
wants now to be called Czechia, even if this is not much easier to write.
Other country name changes that happened since the year 2000. East Timor
changed to Timor-Leste (in 2002 as another official name)
The Hungarian Republic
added Hungary in 2012 as another official name. Libya
changed its name to State of Libya (in 2013 but not recognized) Cape Verde
added Cabo Verde in 2013 as another official name; they speak Portuguese there.
The Islamic Republic of The Gambia
changed its name to Republic of The Gambia in 2017; maybe for image concerns? Yugoslavia
- In 2003, FR Yugoslavia became officially known as the State Union of Serbia and Montenegro (abbreviated SUSM). In 2006, Montenegro seceded from the union and regained independence on 3 June 2006. Capital name change
The capital of Kazakhstan Astana was renamed Nur-Sultan in 2019. Note: * Irritatingly, the IMF Country Data Profile page lists Taiwan (Republic of China) as Taiwan, Province of China.
